Stray inductance detection device of laminated busbar

Abstract

The invention discloses a stray inductance detection device of a laminated busbar. The structure of the device comprises a detection device body, a wiring test interface, a rubber backing ring, a pulse generation bottom box, an adapter frame, a pulse line protection rod, a laminated busbar mounting frame, an anti-electric shock lifting plate and an automatic power-off protection device capable ofigniting and extinguishing arc. The front surface of the detection device body is provided with the wiring test interface and is connected with the wiring test interface in an embedded manner, the upper surface of the rubber backing ring is connected with the lower surface of the detection device body in an attached manner, the pulse generation bottom box is installed on the lower surface of the rubber backing ring, and the adapter frame is arranged on the right surface of the detection device body in a welded manner. Sulfur hexafluoride gas blows to transversely blow and cool an electric arcfor arc extinguishing, the fault that the electric arc on the inner side of the device burns out a wire is avoided, meanwhile, due to insufficient arc extinguishing strength, the device is stopped byguiding forced outage, and fire disasters caused by electric sparks generated on the inner side of the device are prevented.

Description

technical field [0001] The invention relates to the technical field of detection equipment, more precisely, it relates to a stray inductance detection device for laminated busbars. Background technique [0002] The laminated busbar is a composite busbar connected by a multi-layer composite structure. The laminated busbar is widely used in power equipment such as electric power and hybrid traction, electric traction equipment, cellular communication, base stations, etc. The manufacture of laminated busbars needs to pass The device detects and processes the stray inductance on the busbar. However, the current laminated busbar detection equipment has the following disadvantages: [0003] 1. The laminated busbar is placed on the equipment for detection, allowing the current to pass through the busbar for processing, and through the busbar, the stray inductance generated by the equipment is detected to cause arc drainage, and the arc can instantly burn the connecting wires in th...
