Embodiment Construction

[0020] The present invention will be further described in detail below in conjunction with the accompanying drawings.

[0021] see figure 1 , figure 2 , image 3 As shown, the invention consists of a test joint 1, a conductive rod 2 and a stress control unit 3. One end of the test joint 1 is formed as a socket 14 that can be connected with the taper surface of the standard casing of the equipment, and the other end is installed with a stress control unit 3 , and a support tube 10 is installed in the test joint 1 . The conductive rod 2 is made up of a conductive rod and a fixed pin 24. The conductive rod 2 passes through the test joint, and one end is processed into a standard thread 21 connected with the equipment bushing, and the other end is processed into a fixed hole 22 for installing the fixed pin, and there is a Mounting hole 23 connected with test power supply.

[0022] see figure 1 The test joint 1 is molded by high-strength rubber insulating material, the inner ...

Abstract

The invention discloses a withstand test device of a sleeve of looped network cabinet equipment, which comprises a test interface, a conducting rod and a stress control unit. One end of the test interface is formed to be an inserting interface which is connected with the conical surface of a standard sleeve of the switch looped network cabinet equipment, and the other end of the test interface is provided with a stress control unit for controlling the distribution of electric field and enhancing the insulation performance. The conducting rod is penetrated through the test interface; one end of the conducting rod is in screw thread connection with the sleeve of the equipment to realize the electric conduction connection and the fixed withstand test; and the other end of the conducting rod is connected with a test power source. By adopting the connection mode, the withstand test device can meet the requirement of various voltage insulation test items and electric current test items of the looped network cabinet equipment. The withstand test device is simple in structure, convenient in installation, practical and reliable.

Description

technical field [0001] The invention relates to the technical field of cable accessories used in power cable engineering and the technical field of ring network cabinet inspection. Background technique [0002] At present, when the ring network cabinets with standard bushings, prefabricated substations, and cable branch boxes of 35kV (inclusive) and below are subjected to voltage resistance at the factory or on site, the methods of connecting cables and standard cable accessories or applying full insulation devices are mainly used. Insulation test. The main problems of the above two methods are: the method of using cables and standard cable accessories, although the test process can be solved, but the test cost is very high and the size of the test site is very high, and the construction technology of the cable The personnel requirements are very high, especially in the type test; although the method of using the full insulation device test is simple to install, it can only...
