Behind the stable operation of the power system, dry-type transformer temperature controller plays a vital role. In the face of the market numerousDry-type transformer thermostatManufacturers, how to select the most suitable partner for their own needs, is every user needs to carefully consider the issue. The following from a number of key dimensions, to provide you with a comprehensive dry-type transformer temperature controller manufacturer selection strategy.
I. Define your own needs
Before selecting a manufacturer, first of all, you need to have a clear perception of your own needs. Different application scenarios have different requirements for temperature controllers, for example, large substations may need to have high precision, high stability, and can adapt to the complex electromagnetic environment of the controller; and small business distribution room, in order to meet the basic temperature control function on the basis of the product may be more focused on the cost-effectiveness of the product. In addition, it is also necessary to consider the capacity of the transformer, the operating environment temperature range, control accuracy requirements and other factors. For example, if the transformer is running in a high-temperature environment for a long time, it is necessary to choose a temperature controller with good high-temperature resistance and strong heat dissipation capability. After clarifying these requirements, you can initially screen out the manufacturers who can meet the conditions.
II. Assessing product quality and performance
(i) Core functions and technical indicators
The core function and technical index of the product is the key to measure the quality. High-quality dry-type transformer temperature controller should have accurate temperature monitoring ability, can real-time, accurate feedback transformer temperature changes, the error range should be controlled within a very small value. For example, the temperature measurement accuracy of some high-end products can reach ±1℃. At the same time, the controller's control logic should be reasonable and reliable, according to the set temperature threshold, timely and accurately start or close the cooling equipment, such as fans. In addition, the data storage and transmission function should not be ignored, support remote data transmission controller to facilitate the operation and maintenance personnel to grasp the real-time operating status of the transformer, to achieve intelligent management.
(ii) Accreditation and qualifications
The certifications and qualifications obtained by manufacturers are a strong endorsement of their quality. Common authoritative certificates include ISO9001 quality management system certification, which indicates that manufacturers have a perfect quality control system in the production process; UL certification in the United States, European CE certification shows that the product meets international safety standards and performance requirements. If the product has also passed the European environmental protection test (such as RoHS certification), it means that it has also reached a high level of environmental protection. Choose to pass a variety of authoritative certification manufacturers, can to a large extent to protect product quality.
(iii) Product materials and workmanship
The material and manufacturing process of the product directly affect its durability and stability. The shell of the temperature controller should be made of high-quality materials, with good protective properties, such as fire, moisture, corrosion, etc., to adapt to different operating environments. The quality of internal electronic components is also critical, the use of well-known brands, high-quality components, can reduce the product failure rate. In addition, exquisite manufacturing process can ensure the assembly precision and reliability of the product, such as good welding process of the circuit board, can effectively reduce poor contact and other issues.
Third, examine the technical strength of manufacturers
(i) R&D team and innovation capacity
Manufacturers with strong R&D teams are more capable of consistently introducing new products and technologies that meet market demands. Information such as the number of R&D personnel, their professional background and experience, and the percentage of R&D investment can be used to assess a manufacturer's R&D strength. For example, some manufacturers invest more than 10% of their annual revenue in R&D to continuously improve product performance and develop new features, such as adding intelligent diagnostics and fault warning. At the same time, pay attention to the number of patents and technological innovation achievements of the manufacturer is also an important basis for judging its innovation ability.
(ii) Technical support and solution capabilities
In addition to providing high-quality products, manufacturers should have professional technical support and customized solutions capabilities. In the process of project implementation, manufacturers can provide targeted technical solutions according to the user's special needs, such as special installation mode of adaptation, integration with other power equipment. When the product problems, manufacturers of technical personnel can quickly respond to provide remote or on-site technical support to help users solve problems and ensure the normal operation of the transformer.
IV. Analyzing Market Word of Mouth and Cases
(i) Client evaluation and feedback
Through the network evaluation, industry forums, customer interviews and other channels, to understand the manufacturer's customer evaluation and feedback. Focus on other users on product quality, after-sales service, delivery cycle and other aspects of the evaluation, can intuitively feel the manufacturer's reputation in the market. For example, if the majority of users feedback on a manufacturer's product failure rate is low, after-sales service response in a timely manner, it means that the manufacturer is trustworthy; on the other hand, if there is a large number of negative comments about product quality problems and after-sales shirking, you need to be careful in choosing.
(ii) Successful cases and application areas
Check the manufacturer's successful cases and product application areas, you can judge whether it has rich experience and strength. If the manufacturer's products have been applied in large-scale key projects (such as airports, rail transit, large data centers, etc.) and run well, it means that the quality and performance of its products have stood the rigorous test. In addition, understanding the application of the manufacturer's products in different industries also helps to determine the versatility and adaptability of its products.
V. Consideration of after-sales service
High-quality after-sales service is an important factor to ensure the long-term stable operation of the product. When choosing a manufacturer, we should pay attention to whether its after-sales service system is perfect, including after-sales service response time, maintenance cycle, whether to provide regular maintenance services. For example, some manufacturers promise to respond within 24 hours after receiving a fault report, within 48 hours to arrive at the scene for repair; at the same time to provide regular door-to-door inspection services to help users find and solve potential problems in a timely manner. In addition, it is necessary to understand whether the manufacturer to provide product training services to ensure that the user operator can correctly use and maintain the temperature controller.
VI. Comparison of price and value for money
Price is a factor that can not be ignored when choosing a manufacturer, but not simply the price level as a selection criterion, but should be a comprehensive consideration of cost-effective. When comparing the price of products from different manufacturers, it is important to combine product quality, performance, after-sales service and other factors. Sometimes, the price of a slightly higher product, if the quality, functionality and after-sales service has obvious advantages, but more cost-effective in the long run. For example, a higher-priced temperature controller, although the initial purchase cost is high, but because of its good stability, low failure rate, low maintenance costs in the later stages, long service life, the overall cost may be lower.
Selection of dry-type transformer temperature controller manufacturers need to start from their own needs, a comprehensive assessment of product quality, technical strength, market reputation, after-sales service and cost-effective and other aspects. Through in-depth research and comprehensive comparison, in order to select the most suitable manufacturers, for the safe and stable operation of dry-type transformers to provide reliable protection.
