Abstract

The invention relates to an integrated junction device for single-phase kilowatt-hour meter inspection and electric strength test. The integrated junction device comprises a test mounting panel, and a compression joint mechanism used for controlling the position of a kilowatt-hour meter, a kilowatt-hour meter terminal junction box slidably connected onto the test mounting panel, an electric energy junction module and an electric strength test junction module are mounted on the front side of the test mounting panel sequentially from top to bottom; the electric strength test junction module is provided with test junction terminals and contact points, the contact points protrude out of the front side of the test mounting panel, and the electric strength test junction module is arranged in the test mounting panel above the electric energy test junction module. By the aid of the device, electric energy detection and voltage detection can be performed and do not affect each other in the test process.

Description

technical field [0001] The invention relates to the field of electric equipment, in particular to an integrated wiring device for single-phase electric energy meter inspection and withstand voltage test. Background technique [0002] The energy error accuracy test and AC withstand voltage safety test of the electric energy meter are very important in the verification work of the electric energy meter. The former is related to the measurement accuracy of the electric energy meter, and the latter is related to the safe use of the electric energy meter. [0003] At present, the domestic withstand voltage test part and the electric energy verification part adopt the relay isolation method, which is switched according to the need during the test, but due to the small distance between the disconnected contacts of the relay used for isolation, the safe creepage during the withstand voltage test cannot be fully achieved. Due to the high test voltage, the relay is often broken down d...

Problems solved by technology

[0003] At present, the domestic withstand voltage test part and the electric energy verification part adopt the relay isolation method, which is switched according to the need during the test, but due to the small distance between the disconnected contacts of the relay used for isolation, the safe creepage during the withstand voltage test cannot be fully achieved. Due to the high test voltage, the relay is often broken down during the 4kV withstand voltage test, and the electric energy verification part of the electric energy meter is damaged, so that the test equipment cannot work normally. An isolation device for the withstand voltage and electric energy test is urgently needed to ensure the withstand voltage test Will not damage the electric energy verification part of the electric energy meter

[0004] At the same time, when the existing device detects the electric energy meter, often due to operational errors or equipment reasons, the connection point of the electric energy meter of the fixed device is often poorly connected, which affects the expected goal
