Detailed Description

The present invention will be described in detail below with reference to the accompanying drawings and examples.

Referring to the drawings, in one embodiment of the present invention, a current transducer adapted to high voltage includes: place a section of thick bamboo 1, spacing subassembly 2, end cover 3, elasticity brace 4, push pedal 5, through-hole 6, via hole 7 and pellicle 8. Wherein, it is the opening to place 1 one end of a section of thick bamboo, it has a plurality of spacing subassemblies 2 to be the annular distribution on the circumference inner wall of a section of thick bamboo 1 to place, the open end of placing a section of thick bamboo 1 is equipped with rather than sealed complex end cover 3, end cover 3 corresponds the middle part of placing 1 place one side of a section of thick bamboo and is equipped with elasticity and props cover 4, the tip department that elasticity propped cover 4 is equipped with push pedal 5, and push pedal 5 corresponds the elasticity and props the hollow region that the inside region of cover 4 is equipped with a plurality of through-holes 6 constitutes, the region that end cover 3 corresponds elasticity and props the inside of cover 4 is equipped with via hole 7, and be equipped with in the via hole 7 and prevent that water from getting into the pellicle 8 of placing 1 inboard from the outside. For current dampproofing structure, this application adopts seal structure, places a section of thick bamboo 1 and adopts single open structure to when the combination, seal this opening through end cover 3, make lie in place a 1 inside changer body of section of thick bamboo be in the seal environment. And in order to avoid the vibrations that produce in the transmitter working process to placing section of thick bamboo 1 and the installation part causes the influence, so fix the transmitter body through spacing subassembly 2. On one hand, the size of the transmitter is not uniform, and the transmitter can be properly adjusted through the limiting component 2 so as to enlarge the application range of the placing cylinder 1; on the other hand, the vibration damping device plays a role in buffering, and the uniformly distributed limiting assemblies 2 can offset the vibration. The design of through-hole 6, via hole 7 and pellicle 8 can guarantee to a certain extent to ventilate to utilize the air that flows to reduce and place the inside air humidity of a section of thick bamboo 1. And if necessary, the water absorbent placed in the elastic brace 4 can effectively remove moisture.
