technical field

The utility model relates to the technical field of high and low voltage switch cabinets, in particular to a wireless temperature measuring device for a switch cabinet.

Background technique

The switchgear is a kind of equipment connected with high-voltage or low-voltage cables. The outside line first enters the main control switch in the cabinet, and then enters the sub-control switch. Each branch is set according to its needs. It plays the role of on-off, control or protection in power system power generation, transmission, distribution, power conversion and consumption, and is often used in power plants, substations, petrochemicals, metallurgical rolling steel, light industry textiles, factories and mines, and residential quarters, In high-rise buildings and other places, when the high-voltage switchgear is working, part of the electric energy will be converted into heat energy, and the high temperature will bring certain safety hazards to the work of the high-voltage switchgear. Therefore, it is necessary to use a temperature measuring device to monitor the temperature of the high-voltage switchgear. detection.

The Chinese utility model patent with the publication number CN214798285U proposes a high-voltage and low-voltage switchgear with a wireless temperature measurement component. By setting a heat dissipation window, the inside of the switchgear body is convenient for heat dissipation and ventilation. By setting a wireless temperature measurement component and a refrigeration component and The water pump is electrically connected, so that when the internal temperature of the switchgear body exceeds the set value, the water pump and refrigeration components can be started quickly through electrical signal transmission, and the water pump is connected to the water tank and the condensate pipe, so that the condensate is drawn from the inside of the water tank through the water pipe through the water pump , into the inside of the condensing tube, and at the same time, the U-shaped condensing tube is in full contact with the bottom of the cooling plate of the social group on the top of the condensing tube, so that the cooling plate can be cooled rapidly, and the temperature of the electronic components fixedly installed on the front of the mounting plate can be quickly passed The cooling plate conducts to the condensate inside the condensation pipe. By setting the cooling plate as a trapezoidal piece with the lower bottom facing the front of the mounting plate, the heating surface of the cooling plate is larger than the heat conducting surface, so that the heat is quickly directed to the upper bottom surface. The tube runs through the bottom of the water tank, so that the condensate that absorbs the temperature of the electronic components returns to the inside of the water tank. At the same time, the temperature inside the water tank is adjusted through the refrigeration component installed at the bottom of the water tank under the activation of the wireless temperature measurement component, so that the condensate The cycle temperature is lower than normal, allowing for rapid cooling.

However, the applicant has found that the prior art has at least the following problems:

Although the temperature inside the high and low voltage switchgear can be monitored and quickly cooled, the method of cooling the inside of the high and low voltage switchgear by transporting the water in the water tank to the condensing pipe may cause water leakage from the water tank or the condensing pipe. And because the inside of the high and low voltage switchgear is full of circuits, water leakage can easily lead to the internal connection of the high and low voltage switchgear, which will damage the internal parts of the high and low voltage switchgear, and even cause a short circuit to cause a fire and cause irreparable losses. The risk is high and practical. Sex is lower.
