Grinding equipment for overhauling transformer substation knife switch contact

Abstract

The invention discloses grinding equipment for overhauling a transformer substation knife switch contact. The equipment comprises a workbench, a mounting plate is fixedly connected to the side wall ofthe workbench, a containing box is fixedly connected to the side wall of the mounting plate, a motor is fixedly connected to the bottom in the containing box, and an output shaft of the motor extendsout of the containing box and is fixedly connected with a rotating rod; and the end, away from the motor, of the rotating rod is fixedly connected with a grinding wheel, and the side wall of the mounting plate is fixedly connected with a clamp. The workbench is provided with a heat dissipation mechanism used for conducting heat dissipation and cooling on the grinding wheel. The heat dissipation mechanism comprises a wire frame fixedly inserted into the side wall of the rotating rod. The side wall of the containing box is fixedly connected with two permanent magnet strips; and two fixing strips are fixedly connected to the side wall, opposite to the workbench, of the mounting plate. The temperature of the grinding wheel and the temperature of the contact can be effectively reduced, the grinding wheel and the contact are prevented from aging too fast, the service life of the grinding wheel and the service life of the contact are prolonged, and the air quality and the health of workers can be guaranteed.

Description

technical field [0001] The invention relates to the technical field related to substation equipment, in particular to a grinding device for overhauling contacts of switch blade switches in substations. Background technique [0002] The insulators of the open substation are exposed to the outdoor environment. The isolating switch switch needs to be closed and opened. Under the power supply state, the isolating switch switch needs to be kept in the normally closed state. The isolating switch switch is eroded by natural phenomena such as rain in the outdoor environment. Corrosion is easy to occur at the contact contacts. If things go on like this, it will easily lead to poor contact of the isolating switch knife switch contacts, causing contact heating, and in severe cases, power failures. Therefore, it is necessary to regularly repair and polish the contacts, and the existing grinding equipment There are the following problems: [0003] 1. When the existing grinding device is...

Problems solved by technology

[0002] The insulators of the open substation are exposed to the outdoor environment. The isolating switch switch needs to be closed and opened. Under the power supply state, the isolating switch switch needs to be kept in the normally closed state. The isolating switch switch is eroded by natural phenomena such as rain in the outdoor environment. Corrosion is easy to occur at the contact contacts. If things go on like this, it will easily lead to poor contact of the isolating switch knife switch contacts, causing contact heating, and in severe cases, power failures. Therefore, it is necessary to regularly repair and polish the contacts, and the existing grinding equipment There are the following problems:

[0003] 1. When the existing grinding device is grinding the contact, due to the rapid friction between the grinding wheel and the contact, the temperature of the grinding wheel and the contact rises sharply, and the excessive temperature is easy to accelerate the aging of the grinding wheel and the contact , thereby shortening the service life of the grinding wheel and the contact;

[0004] 2. When the existing grinding device is grinding, a large amount of dust will be generated. These dusts float in the air and will affect the air quality of the surrounding environment. If inhaled by the staff, it is easy to cause a series of respiratory diseases and threaten the work. staff health
