Problems solved by technology

However, during the measurement process, due to the different measurement environment, the shunt will be subjected to different degrees of vibration. For the existing DC shunt, the vibration is extremely damaging to the hard equipment, especially under the impact of high current , will be severely damaged and the economy will suffer

Abstract

The invention discloses an anti-vibration direct current shunt for measuring impact current. The shunt comprises a left connecting plate, a right connecting plate and a connecting body. The left connecting plate and the right connecting plate are connected into a whole by the connecting body. The left connecting plate comprises a left conductive block body, a vertically-through connecting hole isformed in the left portion of the left conductive block body, a left connecting bolt is arranged on the upper end face of the left conductive block body, a row of concave groove cavities are formed inthe right portion of the left conductive block body, and openings of the concave groove cavities face the right end. The right connecting plate comprises a right conductive block body, the right partof the right conductive block body is provided with a vertically-through connecting hole, the upper end surface of the right conductive block body is provided with a right connecting bolt, the left part of the right conductive block body is provided with a row of vertically-arranged concave groove cavities, and the openings of the concave groove cavities face the left end. The concave groove cavity of the left conductive block body and the concave groove cavity of the right conductive block body are symmetrically arranged. The device can effectively reduce the vibration damage to the shunt ina vibration environment, enhances the resistance in a mode of extending the connecting body, and meets the impact measurement of impact large current.

Description

technical field [0001] The invention relates to the technical field of research on surge current measurement and calibration equipment, in particular to an anti-vibration DC shunt for surge current measurement. Background technique [0002] Impulse current is very important to the safety performance of electrical equipment, and it is used to test the ability of equipment to withstand transient current. The impulse current generator and its measurement system are the main equipment for simulating the impulse current. It is mainly used in power systems, communication systems, lightning protection component enterprises and railway systems, etc., to conduct electromagnetic compatibility tests of electrical equipment, arrester tests and lightning Impulse current withstand test. [0003] DC shunts are widely used in many circuit devices with direct current, especially circuit devices with large direct current and their testing. [0004] The structure of a general DC fixed-value ...
