Abstract
The utility model relates to a high-voltage electrical cabinet test terminal, key feature: the phenomenon that high-voltage electric connection is unstable or creepage caused by the fact that no proper inspection tool is available or the inspection tool is too simple in an experiment field and the movable metal conductor or the outer-layer cold-shrinkage umbrella skirt is sleeved on the movable metal conductor or the outer-layer cold-shrinkage umbrella skirt is used is avoided, and the problems that the whole test of the electrical cabinet is influenced due to the unstable or creepage of the introduced high-voltage electric connection, and further the possibility of faulty operation of the electrical cabinet is difficult to investigate are fundamentally solved. Therefore, the aim of better performing test is achieved. The utility model discloses simple to operate still has, the accurate purpose in location.
Description
Technical Field
The utility model relates to a test terminal for high-pressure electric power cabinet detects especially relates to a high-voltage electric cabinet test terminal.
Background
With the rapid development of national economic construction, the demand of electric energy is rapidly increased, and how to reliably transmit electric energy from a power plant to each user through transmission equipment of a transformer substation and a distribution substation becomes a new subject of the development of the power industry. In the power transmission process, a high-voltage electrical cabinet is essential basic equipment in power transmission conversion. Therefore, before the high-voltage electric cabinet is put into operation, a series of high-voltage tests and detection verifications must be performed, so that high voltage is introduced. The high-voltage electrical cabinet test terminal is a connecting bridge which is used as a high-voltage end to be introduced into an electrical cabinet. Therefore, how the test terminals are designed is particularly important. However, the existing test terminal on the market is mostly of a simple type, the metal conductor is movable or additionally shrinks, when the test terminal is unstable or creepage because of the introduced high-voltage electric connection, the test of the whole electrical cabinet is influenced, and the test result is interfered. The test is inaccurate, and the trouble can't be got rid of, and the regulator cubicle has probably the problem in the operation process. Once the electrical cabinet is out of order, the associated power system is affected.
Disclosure of Invention
