Abstract

The invention belongs to the technical field of electric power protection equipment and in particular provides a multifunctional protective pressure plate comprising an insulating plate and a conductive plate. The insulating plate is in the shape of a cross or a Chinese character 'Mi', and an insulating pad is arranged on each of a plurality of ends of the insulating plate. A first through hole is arranged at the center of each insulating pad, a thread through hole is arranged in the insulating plate, and the thread through hole is arranged in parallel with the first through hole. An insulating toggle block is arranged on the upper end surface of the conductive plate, and a second through hole is arranged at the center of the conductive plate. A screw is arranged in the second through hole, and a baffle plate is fixedly connected with the screw. The lower end of the screw passes through the second through hole and is threadedly fitted with the thread through hole. A compression spring is arranged between the insulating plate and the conductive plate and sleeves the screw. The conductive plate is between the baffle plate and the compression spring. Conductive columns are arranged on two ends of the conductive plate, and the lengths of the conductive columns are smaller than that of the screw. When one of the first through holes is blocked or dirty, the conductive column at the lower end of the conductive plate is adjusted to cooperate with the different first through holes to ensure the power transmission time.

Description

technical field [0001] The invention belongs to the technical field of electric protection equipment, in particular to a multifunctional protective pressure plate. Background technique [0002] Relay protection and safety automatic devices are the most important secondary equipment in the power system. The protection pressure plate is the bridge for relay protection and safety automatic devices to realize their functions. It is related to whether the protection function and the action outlet can work normally. Depending on the position of the secondary circuit of the inlet protection device, it can be divided into two categories: the protection function pressure plate and the outlet pressure plate. When the system operation mode changes, the protection pressure plate will be switched on and off accordingly. Once the protection pressure plate is mis-operated , misstop, may affect the realization of relay protection and safety automatic device functions, and even cause large-s...
