Problems solved by technology
[0002] The terminal box in the substation is generally installed outdoors, exposed to the wind and the sun all the year round, the temperature difference between day and night in the box is large, it is easy to cause condensation, it is easy to cause corrosion to the screws in the box, resulting in reduced insulation, poor contact, etc.
The existing terminal box is generally equipped with a ceramic heater at the bottom of the box, and the use of a ceramic heater has the following disadvantages: 1. Local heating, and the overall dehumidification effect is not obvious; 2. Contact with the cable and burn the cable; 3. Long-term high temperature in the box , accelerate the aging of the insulation inside the box, and also easily cause the relay to malfunction

The invention relates to the field of relay protection automation technologies, and more particularly to a transformer substation terminal box temperature and humidity constant control system. The transformer substation terminal box temperature and humidity constant control system mainly comprises: a refrigeration host, an air circulation pipeline system and a centralized control unit. The centralized control unit is configured to monitor the temperature and humidity of a transformer substation terminal box and start the air circulation pipeline system which cools hot air drawn from the terminal box through the refrigeration host t, and the refrigeration host further dries the air to form a dry cold air and sends the dry cold air back to the outdoor terminal box of the transformer substation. The system can maintain the temperature and humidity of the terminal box in a set constant environment, and is safe and reliable.
