Fast-plugging high-voltage microammeter

Abstract

The invention discloses a fast-plugging high-voltage microammeter. The fast-plugging high-voltage microammeter comprises a high-voltage microammeter, and further comprises a four-pin plug, a banana plug and a high-voltage lead-out binding post, the four-pin plug is installed at the top of the high-voltage microammeter, the banana plug is installed at the bottom of the high-voltage microammeter, the high-voltage lead-out binding post is installed on a voltage multiplying cylinder, the four-pin plug is in plugging-pulling connection with a tail end plug of a high-voltage outline, the high-voltage lead-out binding post is in plugging-pulling connection with the banana plug, a high-voltage insulation cover is arranged on the outer layer of the banana plug, one end is provided with a first screwed nipple screwed with the high-voltage microammeter, the other end is provided with an elastic expansion metal sheet, one end of the high-voltage lead-out binding post is provided with a second screwed nipple screwed with the voltage multiplying cylinder, and the other end of the high-voltage lead-out binding post is provided with a hollow jack in plugging-pulling connection with the elastic expansion metal sheet. The fast-plugging high-voltage microammeter disclosed by the invention realizes fast-plugging installation through a plug-in plug design, and the elastic expansion metal sheet of the banana plug increases the contact area, ensures good contact and has no induction electricity or arc danger.

Description

technical field [0001] The invention relates to a high-voltage generator pressure doubler barrel microammeter, in particular to a quick-insert high-voltage microammeter. Background technique [0002] In order to be safe, fast and convenient, the power department of the power department, industrial and mining, metallurgy, iron and steel and other enterprises conducts DC withstand voltage test or DC leakage current test on zinc oxide arresters, power cables, transformers, circuit breakers, generators and other high-voltage electrical equipment. The high-voltage microammeter is installed on the high-voltage doubler cylinder and reads the data. [0003] The existing high-voltage micro-ammeter and the pressure doubler cylinder are connected by threads. First, it is inconvenient to quickly assemble and disassemble. When installing and disassembling, the high-voltage micro-ammeter must be rotated multiple times, which is time-consuming and laborious. 2. Frequent assembly and disas...

AI Technical Summary

Problems solved by technology

[0003] The existing high-voltage micro-ammeter and the pressure doubler are connected by threads. First, it is inconvenient to quickly assemble and disassemble. When installing and disassembling, the high-voltage micro-ammeter needs to be rotated multiple times, which is time-consuming and laborious.

2. Frequent assembly and disassembly will easily cause thread wear at the joint, resulting in poor thread contact, resulting in inaccurate measurement data of the high-voltage microammeter

3. The microammeter cannot achieve controllable on-off, and the manual switch has a certain risk of electric shock
