A controller for limiting the temperature inside the switch cabinet

Abstract

The invention discloses a controller for limiting inside temperature of a switch cabinet, and the controller comprises a controller outer box, and further comprises a heat control box, a cold controlbox and a heat absorption tube, wherein the heat control box and the cold control box are arranged inside the controller outer box, the heat absorbing tube is installed outside the controller outer box, the heat control box and the cold control box are separated by a heat insulating layer, a plurality of resistance coils are installed inside the heat control box, a water tank is installed inside the cold control box, a sealed box is installed above the water tank, and one end of the water tank is installed with one end of the heat absorbing tube. The controller of the invention, from the pointof view of the temperature controller itself regulating the internal temperature of the circuit box, provides a temperature to guarantee the normal operation of the circuit box when exceeding the normal working temperature in an extremely cold environment, and delays the burning temperature inside the circuit box through the heat absorption of chemical reaction in an extremely hot environment, sothat the circuit box can be safely used to delay the occurrence of danger.

Description

technical field [0001] The invention relates to the technical field of temperature control, in particular to a controller for limiting the temperature inside a switch cabinet. Background technique [0002] The circuit box has a safe operating temperature range during operation. Excessively high temperature can cause the circuit box to burn, and even affect the surrounding combustible objects, resulting in unpredictable losses. Too low temperature will cause the internal components of the circuit box to lose operation. Ability to cause shutdown and, in severe cases, serious failure of equipment. [0003] At present, the temperature of the circuit box is set through holes on the circuit box, and the temperature inside the circuit box is taken away by the flow of natural wind, or a temperature sensing element is installed in the circuit box to transmit the temperature to the control center in real time. If the temperature exceeds the range time to respond, however such a respo...

Problems solved by technology

[0002] The circuit box has a safe operating temperature range during operation. Too high temperature can cause the circuit box to burn, and even spread to the surrounding combustible objects to cause unpredictable losses. Too low temperature will cause the internal components of the circuit box to lose their operation. Ability to cause shutdown and, in severe cases, serious failure of equipment

[0003] At present, the temperature of the circuit box is set through holes on the circuit box, and the temperature inside the circuit box is taken away by the flow of natural wind, or a temperature sensing element is installed in the circuit box to transmit the temperature to the control center in real time. If the temperature exceeds the range time to respond, however such a response has often already caused serious damage, e.g. fire

In order to reduce the risk of fire caused by too high temperature of the circuit box, or the risk of failure of the circuit box caused by too low temperature, there is currently no good way, and this invention also focuses on solving this problem
