Embodiment Construction

[0020] For the convenience of description, the three-phase equipment used as the experimental object in this embodiment is a three-phase common box voltage transformer, and the experimental object can also be other three-phase equipment. The present invention is used for the embodiment of the test device of three-phase equipment: as Figure 1-4 As shown, it includes an insulating sleeve 2 and a cylinder 3. The cylinder 3 is connected to the lower end of the insulating sleeve 2. The upper end of the insulating sleeve 2 is provided with a primary terminal 1. The primary terminal 1 is used to connect the primary cable to the device. The current is introduced inside, and the lower end of the cylinder 3 is connected with the test object. The inside of the insulating sleeve 2 is provided with a conductive tube 6 , the upper end of the conductive tube 6 is conductively connected with the primary terminal 1 , and the lower end of the conductive tube 6 is fixed by the first pot insulat...

Abstract

The invention provides a testing device for three-phase equipment. The testing device comprises an inter-phase switching operating mechanism. The inter-phase switching operating mechanism is providedwith three guiding rods. The guiding rod is provided with an electric connecting rod. Through a conducting rod, conduction and breaking of an upper conducting end and a lower conducting end of a corresponding phase can be respectively and quickly realized, and furthermore quick switching between conduction and breaking of the tested phase of the three-phase equipment is realized. In testing, switching of the tested phase does not require multiple detachment of a testing device or a primary cable, thereby realizing convenient operation and improving working efficiency.

Description

technical field [0001] The invention relates to a test device for three-phase equipment. Background technique [0002] Before the three-phase common box voltage transformer leaves the factory, it is necessary to test the three phases separately and sequentially. The test device in the prior art can only test one phase after each installation, and the test device needs to be disassembled when testing the other phase. very low. [0003] At present, in order to improve the test efficiency of the test device of the three-phase common tank voltage transformer supporting GIS, those skilled in the art have made targeted research, such as the test device with the publication number CN 202018483 U, which includes three insulating sleeves, and The connecting cylinder connected to the lower end of the insulating sleeve, the upper end of the insulating sleeve is provided with a primary terminal, the insulating sleeve is provided with a conductive rod, the upper end of the conductive ro...
