The structure is simple, the use is convenient, and the test requirement of a production line in batch production of SF6 gas-filled cabinets can be met.
Description
Technical Field
The utility model relates to a mutual-inductor field, a SF6 aerifys voltage transformer performance test frock for cabinet specifically says so.
Background
The existing SF6 gas-filled cabinet is required to be subjected to a withstand voltage test, a partial discharge test, an excitation characteristic test and an error test in production, a mutual inductor in the gas-filled cabinet is required to be connected with a cabinet body part for testing during batch production, the mutual inductor is installed in the cabinet body, the testing operation is inconvenient, the testing period is long, the testing efficiency is low, the labor cost is high, and the actual requirements of batch production cannot be met.
Disclosure of Invention
The utility model provides a simple structure, it is convenient to use, can satisfy SF6 aerify the SF6 of the experimental demand of production line of cabinet batch production and aerify the voltage transformer performance test frock for the cabinet.
The utility model adopts the technical proposal that: the utility model provides a SF6 aerifys voltage transformer performance test frock for cabinet which characterized in that: including high-voltage primary electrode, low pressure shielding electrode, fixed connecting rod and insulating housing, low pressure shielding electrode sets up in high-voltage primary electrode periphery and both all encapsulate in insulating housing, and fixed connecting rod coaxial cross-under is in high-voltage primary electrode, and fixed connecting rod's top is through nut locking crimping on the insulating housing top, and insulating housing grafting voltage transformer inside socket is worn out to fixed connecting rod's bottom.
Furthermore, a flange is designed at the bottom of the insulating shell and is used for supporting or connecting the voltage transformer.
Furthermore, the plug is integrally designed at the bottom of the insulating shell, the socket inside the voltage transformer comprises a socket hole and a plug port, the plug port is located at the bottom of the socket hole, the plug correspondingly matches with the plug socket hole, and the fixed connecting rod penetrates out of the plug port.
Furthermore, a circular boss is integrally designed at the bottom of the insulating shell, and a circular counter bore corresponding to the circular boss is formed in the opening of the socket inside the voltage transformer.
Further, the insulating shell is an epoxy resin cast insulator.
The tool is of an integrated structure formed by packaging a high-voltage primary electrode and a low-voltage shielding electrode through an insulating shell of an epoxy resin pouring insulator, and penetrates through a fixed connecting rod in the high-voltage primary electrode to extend out of the bottom of the insulating shell to be poured with a voltage transformer and an epoxy mixture in an inflation cabinet to form an integrated test tool. The head of the insulator is inserted into an internal socket of the mutual inductor to be directly plugged, the top of the fixed connecting rod is screwed down to tightly press the mutual inductor and the tool on the top of the insulating shell, and then follow-up tests can be carried out. The test tool is small in size and compact in structure, and partial discharge does not exist under the test voltage of the mutual inductor. Adopt the pouring of integral type epoxy, insulating strength is high, and is not fragile. The replaceable different fixed connecting rods and the mutual inductor sockets with different specifications are matched for testing, the test operation is convenient, the reliability and the accuracy of the test are improved, the installation time in the test process is reduced, and the resources are saved.
