specific Embodiment 1

[0010] Such as figure 1 A specific embodiment is shown, which includes a cylinder body 2 and an inflatable tube 5. Each of the two ports of the cylinder body 2 is provided with a connecting piece for connecting with a secondary wiring board. Flange 1 on 2, the compression flange 3 used to compress the secondary junction box and the bolt and nut assembly 4 used to connect the two flanges, one end of the inflation tube 5 communicates with the cylinder body 2, and the other end is provided with a Flange for relay connection 6. This specific embodiment is aimed at the secondary wiring board with a sealing groove, and the outer surface of the flange 1 can be processed into a plane with a better finish.

specific Embodiment 2

[0011] Such as figure 2 Another specific embodiment shown is different from the first embodiment in that the inner sides of the two flanges 1 are provided with sealing grooves 7 . This specific embodiment is aimed at those without sealing grooves on the secondary wiring board, which can ensure sufficient airtightness.

[0012] How to use: Put the sealing ring into the sealing groove 7 first, then put the secondary wiring board on the flange 1 of the main part of the leak detection tool, then put the compression flange 3 on it, and use long enough bolts and nuts Component 4 fixes the two flanges and presses the secondary wiring board, installs another secondary wiring board in the same way, installs a density relay on flange 6, and fills it with special gas to detect leaks.

Abstract

Disclosed is a leak detection equipment of mutual inductor secondary patch board, including cylinder and inflation tube. Two connectors for connecting secondary patch board are respectively positioned on each of both ports of the cylinder, and one end of the inflation tube is connected to the cylinder with the connector positioned on the other end for connecting density relay. The invention can simultaneously detect two secondary patch boards with saved leak detection gas and improved leak detection efficiency, overcoming the problems of the present leak detection equipment such as single and high cost.

Description

(1) Technical field [0001] The invention relates to a leak detection tool, in particular to a leak detection tool for a transformer secondary wiring board. (2) Background technology [0002] The existing leak detection tool for the transformer secondary terminal block is sealed by putting the open end into the terminal block sealing ring, filling a certain amount of gas inside, and performing an air leakage test to achieve the purpose of detecting whether there is an air leak. Only one wiring board can be installed for inspection at a time, and a certain amount of special gas must be used for each inspection, which cannot meet the production needs and cause waste of manpower and material resources. (3) Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a leak detection tool for a transformer secondary connection board that can detect two secondary connection boards at the same time. [0004] In order to solve the a...
