Mouse blocking plate special for transformer substation

Abstract

The invention relates to a power supply safety device, in particular to a mouse blocking plate special for a transformer substation. The mouse blocking plate special for the transformer substation is characterized in that a rectangular mouse blocking plate body and adsorption mechanisms are arranged, fixing frames are arranged on the two sides of the mouse blocking plate body respectively, the fixing frames are provided with mounting holes used for connecting the fixing frames with a wall and are hinged to the lower end of the mouse blocking plate body, the adsorption mechanisms and springs are arranged at the upper ends of the fixing frames, magnetic blocks are correspondingly arranged at the upper end of the mouse blocking plate body, each adsorption mechanism is provided with a manual control circuit and a fire disaster linkage control circuit, and the manual control circuits and the fire disaster linkage control circuits are connected in parallel. According to each manual control circuit, a manual switch and an electromagnet are connected in series and then connected with a power source to form a loop. Each fire disaster linkage control circuit is provided with a relay, a return button and at least two starting buttons, two normally-closed contacts of each relay are connected with the power source and the corresponding manual control circuit respectively, the corresponding starting buttons are connected in parallel, and a control contact, the return button of each relay and the corresponding parallel starting buttons are connected in series and then are connected with the power source to form a loop. The mouse blocking plate special for the transformer substation has the advantages that the starting mode is simple and fast, the mouse blocking plate can be in linkage with a fire fighting system, and hidden evacuation danger is avoided.

Description

technical field [0001] The present invention and the safety device for power supply are specifically a special rat-stopping board for a substation that is easy to operate, safe to use and used for fast evacuation of rats. Background technique [0002] As we all know, in warehouses, substations, factory buildings and other buildings, especially in industrial buildings located in the suburbs, it is generally required to set up mouse guards at the external entrances and exits of the buildings to prevent small animals such as mice from entering the room and destroying stored items or production equipment. , The mouse baffle is a plate-shaped obstacle arranged at the door, the height is higher than the ground, and the width is the same as the door. It is used to prevent small animals such as mice from entering the room. The mouse guards used in existing substations mainly adopt fixed type, spring automatic homing type, push-down type and bolt-fixed type. During use, it is found t...

AI Technical Summary

Problems solved by technology

The mouse guards used in existing substations mainly adopt fixed type, spring automatic homing type, push-down type and bolt-fixed type. During the use, it is found that they have many shortcomings. First, it is inconvenient to disassemble during emergency evacuation; The first is that it cannot be kept open during emergency evacuation; the third is that the track is easily blocked and cannot be opened during emergency evacuation;
