The temperature display controller can be installed on the epoxy resin dry-type (potting) pressure device to display and control the operating temperature of the transformer winding, so as to ensure the normal service life of the transformer. The temperature sensor PT100 platinum resistance is inserted into the low-voltage winding to obtain the temperature signal. After the circuit processing, the temperature of each phase winding is displayed on the control board. It has the functions of temperature setting, manual / automatic start and stop of fan, sending out fault, overtemperature acousto-optic signal alarm, overtemperature automatic trip and so on. It has the anti electromagnetic interference ability stipulated by the state. At the same time, intelligent computer interface is reserved to realize remote control.

The characteristics:

The main characteristics of sealed transformers include high safety, low noise, small size, wide applicability, high reliability, environmental protection and energy saving, and strong adaptability.

High security

Sealed transformers form a sealed structure by immersing the core and coil of the transformer in a special epoxy resin, avoiding direct contact between electrical components and reducing the risk of short circuits and leakage, thereby improving the safety of the equipment.

low noise

There is no air gap inside the sealed transformer, and the coil and iron core are tightly integrated. The magnetic field has no leakage, so the noise level is lower, which is about 10 decibels lower than traditional transformers.

Small volume

The sealed transformer has a compact internal structure without a refrigeration system, making it small in size, light in weight, and easy to install. It is particularly suitable for situations with limited space or unfavorable indoor layout.

Wide applicability

Sealed transformers are suitable for various places, such as industrial and mining enterprises, shopping malls, hotels, hospitals, subways, etc. Due to its high safety and low noise characteristics, it is more suitable for high-end residential areas, schools, libraries, and computer rooms that require high noise and safety requirements.

high reliability

The sealed transformer adopts a sealing structure, effectively preventing external environmental erosion and improving the reliability of the equipment. Dry sealed transformers do not require the use of insulating oil, reducing environmental pollution and energy waste, and have high environmental and energy-saving characteristics.

Strong adaptability

Sealed transformers are suitable for various harsh environments, such as high temperature, high humidity, and high dust, and have strong environmental adaptability. Its compact structure, simple maintenance, and reduced operating costs
