Abstract
The invention discloses a temperature control safety system for an electrical control cabinet, which comprises an electrical control cabinet, temperature sensors, a control chip, cooling fans, a branch PCC switch, a master PCC switch, an alarm device and an LED display. The temperature sensors are disposed in insulating plate for installing respective electrical appliance modules in the electrical control cabinet, and transmit the temperature of the electrical appliance modules monitored in real time to the control chip. The control chip sets a safe temperature range and a plurality of over-temperature thresholds for each electrical appliance module. The backboards, corresponding to respective electrical appliance module, of the electrical control cabinet are equipped with the cooling fans which are connected with the control chip. When the temperature sensors detect the temperature of a certain electrical appliance module is beyond the first over-temperature threshold, the control chip starts the corresponding cooling fan to cool the certain electrical appliance module.
