Description

Technical Field

[0001] The utility model belongs to the technical field of electric power auxiliary tools, and particularly relates to a secondary wire track device linked with a random-end PT trolley. Background Art

[0002] The voltage transformer configured at the generator outlet of a pumped storage power station is relatively large in volume, and the weight of the PT (voltage transformer) trolley can reach 80 kg. When overhauling and conducting preventive tests on the voltage transformer, it is necessary to pull out the PT trolley from the cabinet track and perform operations such as short-circuiting the secondary wiring of the PT. There are many lines in the secondary circuit and the wiring is relatively complex. Considering the actual situation and analyzing the overhaul situation of the PT trolley in the power station over the years, when the PT trolley is pushed in and out, the secondary wiring of the PT will be wound around the contacts of the PT trolley. If brute force is used during operation, it will cause damage to the secondary wire and breakage, resulting in serious consequences such as the failure to meet the unit startup conditions. At present, the fixing method of the secondary wire of the PT trolley is only fixed by tying straps, which cannot permanently solve the risks of secondary wire jamming and breakage.

[0003] The traditional fixing method of the secondary circuit wire of the PT trolley is to bundle it into a wire harness. When the machine-end PT trolley is pushed in and out, the bundled wire harness moves irregularly with the PT trolley, which is extremely likely to cause jamming and breakage of the secondary circuit. Especially when the PT trolley is pushed in, the PT trolley is closed, and it is impossible to observe the position of the secondary wire of the PT with the naked eye, which cannot guarantee the overhaul quality of the unit.

[0004] Therefore, it is necessary to design a secondary wire track device that moves with the PT trolley. Content of the Utility Model

[0005] The technical problem to be solved by the utility model is to solve the deficiencies in the existing technology and design a secondary wire track device linked with a random-end PT trolley. This secondary wire track device linked with a random-end PT trolley has a simple structure and is convenient to use; it solves the problem that when the PT trolley moves, the secondary wiring of the PT will be wound around the contacts of the PT trolley, and brute force operation causes damage to the secondary wire and breakage.

[0006] The technical solution adopted by the utility model to solve its technical problems is as follows:
