Problems solved by technology

The arc suppression cabinet controller is a controller used to control switching and adjustment control when a ground fault occurs in the power grid, but the arc suppression controller generally can only operate at a temperature lower than 60°C or higher than -10°C. If the ambient temperature is too high or too low, it may cause the arc suppression controller to fail to operate normally.
The arc overvoltage state will cause the controller to heat up rapidly, affecting its normal use, and even causing danger, causing damage to the power grid

Abstract

The invention discloses an arc extinguishing cabinet controller, comprising a shell. A refrigeration chamber is arranged at the top of the shell, a ventilation opening is formed in the top of the refrigeration chamber, a first fan is arranged in the ventilation opening, a semiconductor refrigerator is arranged in the refrigeration chamber, a red copper rod is arranged at the cold end of the semiconductor refrigerator, and a heat absorption piece is arranged at the bottom end of the red copper rod. Arc light is sensed through the arc light sensing probe. The signal is sent to the processor module. The processor module controls an external switching value to open the optocoupler isolation circuit, and protects the circuit board. When the circuit fails and the temperature of the circuit rises, the temperature sensor senses the temperature of the cable and sends information to the processor module, the processor module controls the semiconductor refrigerator and the air cylinder to work, the air cylinder pushes the installation plate to drive the circuit board to stably ascend and make contact with the heat absorption piece, the cold end of the semiconductor refrigerator conducts heatof the heat absorption piece through the red copper rod to cool the circuit board, controller safety is protected, and maintenance cost is reduced.

Description

technical field [0001] The invention relates to the field of controllers, in particular to an arc suppression cabinet controller. Background technique [0002] With the continuous and rapid development of the power system, in order to ensure the safe operation of the power supply line, the arc suppression cabinet has been widely used, and the requirements for the arc suppression cabinet controller for controlling the work of the arc suppression cabinet and displaying the working status of the arc suppression cabinet are also required. Addition, the existing arc suppression cabinet has a good indication of the current working state of the arc suppression cabinet, can display the voltage value and the line selection line, and can also display the simulation diagram of each switching value, which is convenient to use. The arc suppression cabinet controller is a controller used to control switching and adjustment control when a ground fault occurs in the power grid, but the arc ...
