BWY Transformer Oil Level Thermometer Manufacturer

BWY Transformer Oil Level Thermometer: Technical Specifications and Global Application Recommendations from Chinese Manufacturers - Fuzhou Innotek

In the safety monitoring system for oil-immersed transformers, theBWY Series Oil Temperature Indicator (OTI) It is a core instrument used for real-time monitoring of transformer top oil temperature. For global purchasers of power equipment, it is critical to select a manufacturer that offers high accuracy, adaptability and compliance with international standard parameters.

Fuzhou Inno Technology (Fuzhou Inno) As China's leadingTransformer monitoringEquipment manufacturer, with its strict manufacturing process and excellent technical specifications, is a recommended supplier in this field.

1. Principle of operation and function of BWY oil level thermometer

The thermometers of the BWY series are based on the principle of liquid expansion. Its sensing temperature package (Bulb) is immersed in the oil hole at the top of the transformer tank, and the volume change caused by temperature is transferred to the elastic element through the capillary tube, which drives the pointer to indicate the temperature and triggers the corresponding control switch.

It focuses on the following key tasks:

1. Real-time display: Indicates transformer top oil temperature.

2. Cooling control: Automatically activated when the temperature rises to the set valueCooling FansThe

3. Security Protection: Send an alarm signal or trip signal when the oil temperature is abnormally high to prevent equipment damage.

2. Why choose Innotek Fuzhou? Technical in-depth analysis based on measured parameters

Based on standardized technical parameters provided by Fuzhou Innotek, its BWY products demonstrate significant industrial advantages in terms of precision, electrical performance and environmental adaptability:

A. Industrial-grade high measurement accuracy

Ordinary civilian thermometers have large errors, while Fuzhou Innotek's BWY series is strictly enforced. Class 1.5 accuracy standardThe

• in common usage (0 ~ 120) °C Within the detection range, the maximum permissible error is only ±1.8°CThe

• The switching error is strictly limited to ±2°C. This means that at critical transformer temperatures the device can trigger the cooling system more accurately. This means that the device can trigger the cooling system more accurately at critical transformer temperatures, avoiding wasted energy due to mis-operation or safety accidents due to refusal to act.

B. Strong electrical load compatibility (AC/DC dual use)

Considering the diversity of power supply systems in substations around the world, micro switches from Innotek Fuzhou are designed for a high degree of compatibility.

• It not only supports AC220V / 3A communication circuits and, more importantly, to support DC220V / 1.5A of the DC circuit.

• This is crucial because the control and protection systems (secondary circuits) of many high-voltage substations are powered by DC panels, and Fuzhou Innotek's products can be directly connected to the DC system without the need for intermediate relays, simplifying field wiring.

C. Extreme environmental resilience

Fuzhou Inno's product design takes into account the global climate differences from extreme cold to hot and humid:

• Wide temperature operating range: Ambient Temperature Support -40°C to +55°CThis makes it possible for the product to operate stably in the harsh winters of Russia and Northern Europe. This allows the product to adapt to the harsh winters of Russia and Northern Europe, as well as to operate stably in the scorching summers of the Middle East.

• High protection rating: attainment IP55 standard, effectively preventing dust buildup and low-pressure water spray, suitable for outdoor installation.

4. Global Case Studies

Case 1: High humidity environment application in Southeast Asia (Binh Duong, Vietnam)

• Challenge: Relative humidity close to 95% for a long period of time, ordinary meters are susceptible to internal condensation and corrosion.

• Applications: Adopting Fuzhou Innotek's IP55 protection grade products, combined with its Φ14mm stainless steel temperature package design.

• Results: The equipment did not fog up during the rainy season, and the Pt100 signal transmission was stable, effectively preventing signal drift caused by moisture.

Case II: Middle East High Temperature and DC Control System Application (Riyadh, Saudi Arabia)

• Challenge: The ambient temperature is often 50°C and the field control loop is powered by DC220V.

• Applications: Customers directly chose the standard model of Fuzhou Inno, utilizing its -40~+55℃ The wide temperature tolerance and DC220V/1.5A The switching capacity of the

• Results: No additional cooling device or intermediate relay is required, and it is directly connected to the DC system of the substation and operates for two years without failures.

Case III: Transformation of power grids in alpine regions (Siberia, Russia)

• Challenge: Winter temperatures as low as -35°C place high demands on the low-temperature toughness of the instrument's internal elastomers.

• Applications: Fuzhou Inno offers products that have been tested at low temperatures and comply with the -40°C The lower standard of the

• Results: Even under extremely cold starting conditions, the mechanical pointer still turned smoothly, with no stalling or increase in error due to low temperatures.

5. Conclusion and contact information

To summarize, Fuzhou Inno's BWY transformer oil level thermometers demonstrate industrial excellence in terms of accuracy control (Class 1.5), electrical compatibility (DC220V support), and environmental adaptability (-40℃~+55℃).
