Problems solved by technology

The determination of the explosion pressure is directly related to the pressure value of the overvoltage test, and when the explosion pressure of the motor is measured in the rotating state, it is often necessary to directly drive the tested motor through the power supply, and when the power supply is directly driven, the equivalent winding cannot be used. Drive the motor under test instead of the model
When there is no high-voltage distribution of 6kV, 10kV or above in the laboratory, it is also impossible to measure the explosion pressure of the tested motor in the rotating state

Abstract

The invention relates to a motor dragging type explosion-proof motor explosion pressure measuring test device and a method. The device comprises a power cable leading-in device, a low-voltage grade dragging motor, a connecting piece, a high-voltage grade tested motor, an explosion-proof test groove, a supporting platform, a dragging motor height adjusting bracket, a power cable, a pressing device,a cable sealing ring and an explosion-proof test groove base. Through the method disclosed by the invention, the low-voltage grade dragging motor is used for driving the high-voltage grade tested motor, so that the high-voltage grade tested motor can be tested under a rotary state. The requirements on a test power distribution source can be obviously reduced, and the construction efficiency of the flameproof shell voltage-withstanding test device is improved.

Description

technical field [0001] This patent application belongs to the technical field of withstand voltage test of explosion-proof motor casing, and more specifically relates to a motor-driven explosion-proof motor explosion pressure measurement test device and method. Background technique [0002] Flameproof electrical equipment refers to electrical equipment with a flameproof enclosure, and the explosion-proof mark is "d". The flameproof enclosure refers to the enclosure that can withstand the internal explosion pressure and prevent the explosion flame from spreading to the surrounding environment. The housing pressure test in the type test of the flameproof motor includes explosion pressure (reference pressure) measurement and overpressure test, where the explosion pressure measurement needs to be tested in a static and rotating state. The determination of the explosion pressure is directly related to the pressure value of the overvoltage test, and when the explosion pressure of...
