Novel remote circuit breaker for coal mine electromechanical equipment

Abstract

The invention discloses a novel remote circuit breaker for coal mine electromechanical equipment. The novel remote circuit breaker comprises a main body box, a right side of the main body box is fixedly connected with a remote controller box; an infrared remote controller is arranged in the remote controller box, an upper partition plate, a lower partition plate and a mounting frame are fixedly connected to a back face of the main body box, filter screens are fixedly connected to the two ends of the upper partition plate and the two ends of the lower partition plate correspondingly, and an infrared receiver is fixedly connected to a lower surface of the upper partition plate. The invention discloses the novel remote circuit breaker for coal mine electromechanical equipment. Supporting legsand a moisture-proof pad are arranged; the main body box is prevented from being affected with damp, by setting a drying net, air entering the main body box can be dehumidified; by arranging slidinggroove blocks, the drying net can be conveniently disassembled and cleaned, by arranging a filter net, dust in air can be blocked and adsorbed, and by arranging the mounting frame, the circuit breakercan be fixed, so that the novel remote circuit breaker for the coal mine electromechanical equipment has waterproof and dustproof effects.

Description

technical field [0001] The invention relates to the technical field of circuit breakers, in particular to a novel remote circuit breaker for coal mine electromechanical equipment. Background technique [0002] Coal mines refer to places rich in coal resources, which are generally divided into underground coal mines and open-pit coal mines. When the coal seam is far away from the surface, it is generally selected to dig underground roadways to mine coal. This is an underground coal mine. When the distance between the coal seam and the surface is very close When mining coal, it is generally chosen to directly strip the surface soil layer to excavate coal. This is an open-pit coal mine. Coal is the most important solid fuel and a kind of combustible organic rock. According to the degree of coalification, it can be divided into peat, lignite, bituminous coal and anthracite. The fourth category, coal seams are often accompanied by the existence of gas, methane, etc., which are li...

Problems solved by technology

[0003] A circuit breaker refers to a switching device that can close, carry and break current under normal circuit conditions and can close, carry and break current under abnormal circuit conditions within a specified time. Circuit breakers can be used to distribute electrical energy. Start the asynchronous motor frequently, protect the power line and the motor, and automatically cut off the circuit when they have severe overload, short circuit and undervoltage faults. Its function is equivalent to the combination of a fuse switch and an overheating relay. , and generally do not need to change parts after breaking the fault current. At present, it has been widely used. In underground coal mines, there are a lot of dust and moisture in the air, and the existing general circuit breakers cannot effectively prevent water and dust. , so that there is a great potential safety hazard when the circuit breaker is in use
