Abstract

The invention relates to a single-phase multifunction electric energy meter calibration stand automatic short circuit automatically connecting device, comprising a box body (1), a current wire connecting terminal component (2) and a voltage wire connecting terminal component (3); the front side of the box body (1) is fixedly connected with an assistant terminal needlebar component (5) which comprises an assistant terminal needlebar body (5.1), an assistant terminal probe (5.2), a circuit board (5.3) and a socket (5.4); the assistant terminal needlebar body (5.1) is fixedly connected with the front side of the box body (1), the assistant terminal probe (5.2) is vertically inserted in the assistant terminal needlebar body (5.1), the lower end of the assistant terminal probe (5.2) is connected with the circuit board (5.3), and the socket (5.4) is connected with the circuit board (5.3) and is arranged outside the box body (1). The invention can realize the automatic contact joint of the current, the voltage and the assistant wire connecting terminal in the whole electric energy meter testing process at one time, and the functional reliability is high when heavy current passes through. The device of the invention has the automatic wire connecting function, the automatic short circuit function and the socket attaching function.

Description

(1) Technical field [0001] The invention relates to an automatic wiring device for electric energy meter testing. It is suitable for the wiring of the electric energy meter calibration on the calibration platform. It belongs to the technical field of electrical measuring instruments. (2) Background technology [0002] At present, there are mainly two methods of test wiring on the electric energy meter calibration platform: one is to use the terminal post on the test device to directly push against the fastening screw of the electric energy meter terminal button seat by the spring, and connect the electric power through the fastening screw. flow to the copper terminals of the energy meter. In this method, under the condition of passing a large current, due to the large contact resistance between the terminal post on the test device and the set screw, the temperature of the contact point will be too high under the situation of passing a large current, which will damage the e...
