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 DC shunt for measuring impulse current, which comprises a left connecting plate, a right connecting plate and a connecting body, the connecting body connects the left connecting plate and the right connecting plate as a whole; the left connecting plate includes a left conductive block body, the left part of the left conductive block is provided with up and down transparent connecting holes, the upper end of the left conductive block is provided with left connecting bolts, and the right part of the left conductive block is provided with a row of concave grooves, the concave grooves The opening faces the right end; the right connecting plate includes a right conductive block body, the right part of the right conductive block body is provided with a connection hole that is transparent up and down, the upper end surface of the right conductive block body is provided with a right connecting bolt, and the left part of the right conductive block body There is a row of concave grooves arranged up and down, and the opening of the concave grooves is towards the left end; the concave grooves of the left conductive block and the concave grooves of the right conductive block are arranged symmetrically; this device can effectively reduce vibration in the environment. The shunt is damaged by vibration, and by extending the connecting body, the resistance is enhanced to meet the impact measurement of the impact of 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 ...
