Problems solved by technology
[0006] In order to make up for the deficiencies of the prior art, the present invention proposes a non-interventional voltage modulation device. The present invention is mainly used to solve the problem that the existing voltage modulation device generally includes a voltage modulation device body and multiple pins, and during use, If there is excessive external force extrusion, the pins will be bent and deformed, which will cause the pins to deform and break. In serious cases, there may even be a problem that the pins are bent and touched to cause a short circuit.

Embodiment approach
[0029] As an embodiment of the present invention, the arc-shaped metal plate 44 free end is provided with a second projection 49 against the insulating protective sleeve 41 on the insulating protective sleeve 41. By the arrangement of the second projection 49, it is possible to clamp the insulating protective sleeve 41 on the maintenance arcuate metal plate 44, while increasing its structural stability, there is a gap between the curved metal plate 44 and the insulating protective sleeve 41. Improve the heat dissipation performance of the curved metal plate 44 towards the pin 3 side.
[0030] As an embodiment of the present invention, the arc-shaped metal plate 44 is made of a nickel-titanium memory alloy, and the free end of the arc-shaped metal plate 44 is fixedly disposed on one side of the insulating protective sleeve 41, and the guide tube 45 is provided. The guide cartridge 45 is arranged in the front and rear direction and is attached to the elastic traction rope 46. Since ...

The invention belongs to the technical field of voltage modulation devices, and specifically relates to a non-interventional voltage modulation device, which includes a voltage modulation device body, a mounting base is provided on the front end side of the voltage modulation device body, and a mounting base is fixedly connected to the mounting base. There are multiple groups of pins, and the pins are all covered with protective devices; the protective device includes an insulating protective cover set outside the pins, and the front, rear and middle parts of the insulating protective cover are fixed with blocking blocks; Through the setting of the blocking block, the bending range of the pin can be realized by blocking between adjacent blocking blocks, thereby avoiding the problem of excessive bending and breaking of the pin, and avoiding the short circuit caused by the contact of adjacent pins question.
Description
Technical field [0001] The present invention belongs to the technical field of voltage modulation devices, and is specifically a non-invasive voltage modulation device. Background technique [0002] Power companies need to master the topology of low-voltage power supply lines in the area, in order to make accurate governance, accurate fault positioning and load balancing on line damage, and the topology relationship between the line will change with business expansion or technical transformation, therefore Technologies can easily generate accurate topology relationships. [0003] The main technical solution for the current line topology recognition is current disturbance technology. Current disturbance technology, producing a large current of dozens of ampere or even hundreds of amps near the zero point, realizing the line topology recognition by detecting voltage current in the line or change in zero. This technique will impact the grid, causing the malfunction of the protection...
