Problems solved by technology

[0003] In the prior art, embedded parts and terminal blocks are usually made of metal materials. Large transformers are fixedly connected to embedded parts through terminal blocks. When the transformer is installed with a grounding device, the terminal block connecting the transformer and embedded parts Usually, a welding machine is used to directly weld on the embedded parts. However, the welding machine is not only inconvenient to carry, but also requires on-site power connection when using it. Therefore, it is time-consuming and laborious to use a welding machine to weld the terminal block to the embedded parts, which brings great inconvenience to the staff. many inconveniences

Embodiment Construction

[0024] Such as figure 1 As shown, a grounding device for a large-capacity power transformer includes a mounting rod 1 , an expansion member 2 , a clamping device 3 , and a contraction member 4 . Wherein, the mounting rods 1 are arranged left and right, and both ends of the lower end surface of each mounting rod 1 are fixedly connected with outriggers 5 . After the two installation rods 1 are placed in the pre-buried pit, by inserting the legs 5 into the soil, the two installation rods 1 can be prevented from moving in the pre-buried pit. The telescopic parts 2 are arranged in parallel between the two installation rods 1 in multiple groups, and the two installation rods 1 are connected through the telescopic parts 2 . Adjusting the length of the telescopic member 2 enables the two installation rods 1 to be freely combined and installed according to the size of the grounding grid required by the construction pit and the supporting substation equipment. The contraction part 4 i...

Abstract

A grounding device of a high-capacity power transformer comprises mounting rods which are arranged in pairs and are connected in a sliding mode through multiple sets of telescopic pieces, wherein each telescopic piece comprises a first connecting rod, the first connecting rod is in sliding fit with a second connecting rod, and the other ends of the first connecting rod and the second connecting rod are fixedly connected with a mounting rod; a clamping device is fixed to each telescopic piece and comprises a mounting block and a clamping plate, a mounting cavity is formed in each mounting block, one end of each clamping plate is connected with a fixed rod, each fixed rod freely extends into the corresponding mounting cavity and is connected with a movable plate, each movable plate is in threaded connection with a first threaded rod, and the first threaded rods are rotatably mounted on the mounting blocks; and a contraction piece comprises the second threaded rod, one end of each second threaded rod is rotatably connected with the corresponding mounting rod on one side, and the other end of each second threaded rod freely penetrates through the corresponding first connecting rod and is in threaded connection with the corresponding second connecting rod. According to the grounding device of the high-capacity power transformer, great convenience is brought to a user to connect the transformer and the grounding device together.

Description

technical field [0001] The invention relates to the technical field of transformers, in particular to a grounding device for a large-capacity power transformer. Background technique [0002] When installing large-capacity power transformers, in order to avoid electric shocks for ground personnel, grounding devices are usually installed underground. The grounding devices usually include embedded parts buried underground and terminal blocks that connect the embedded parts with the transformer. [0003] In the prior art, embedded parts and terminal blocks are usually made of metal materials. Large transformers are fixedly connected to embedded parts through terminal blocks. When the transformer is installed with a grounding device, the terminal block connecting the transformer and embedded parts Usually, a welding machine is used to directly weld on the embedded parts. However, the welding machine is not only inconvenient to carry, but also requires on-site power connection whe...
