A mining explosion-proof permanent magnet synchronous frequency conversion traction motor wiring device

Abstract

The invention discloses a mining explosion-proof permanent magnet synchronous frequency conversion traction motor wiring device, which comprises a machine base, a stator winding, a wiring bolt and an insulating sleeve; the stator winding is assembled in the cylinder wall of the machine base, and is connected with the One of the openings of the base is provided with a preset distance; a first through hole penetrating through the cylinder wall is provided in the preset distance, and the insulating sleeve is fixed outside the cylinder wall of the base through the first through hole so that The bottom end of the insulating sleeve protrudes into the cylinder wall; the wiring bolt penetrates and is fixed in the insulating sleeve so that the upper end and the lower end of the wiring bolt are respectively exposed to the top end and the bottom end of the insulating sleeve. The invention solves the problem that the space of the junction box of this kind of motor is compressed, the terminal cover and the special stop gasket cannot be arranged, and the electrical clearance and creepage distance of the terminal cannot meet the standard requirements, thereby solving the problem that the improved coal mine transport locomotive cannot be designed. The problem of mine explosion-proof permanent magnet synchronous variable frequency traction motor, but also simplifies the device and reduces the cost.

Description

technical field [0001] The invention belongs to the technical field of electric motors, and in particular relates to a mining explosion-proof permanent magnet synchronous frequency conversion traction motor wiring device installed in the front of an improved coal mine transport locomotive. Background technique [0002] Mining explosion-proof permanent magnet synchronous frequency conversion traction motor is a traction motor used in the locomotive locomotive used in coal mines to provide traction power for electric transport locomotives. Mine explosion-proof permanent magnet synchronous frequency conversion traction motor wiring device is the only and important device to realize the effective connection between the internal circuit of the motor and the external circuit. Through this device, the power grid or power supply current can be effectively input into the motor, so as to realize the connection of the motor. Drive function (conversion of electrical energy into mechanic...

Problems solved by technology

[0005] The purpose of the present invention is to overcome the deficiencies of the prior art, and provide a mining explosion-proof permanent magnet synchronous variable frequency traction motor wiring device. Through structural improvement, it solves the problem that the space of the junction box of this kind of motor is compressed, and it is impossible to arrange terminal sleeves. The stop gasket, terminal clearance and creepage distance cannot meet the standard requirements, thus solving the problem that the mining flameproof permanent magnet synchronous variable frequency traction motor in the front of the improved coal mine transport locomotive cannot be designed, and it also simplifies the device, reducing costs
