Problems solved by technology

There are many types of current transformers, among which the feed-through current transformer is the most commonly used one. However, when the existing feed-through current transformers are disassembled and overhauled, the busbar needs to be disassembled to remove them, which is very cumbersome.

Embodiment Construction

[0020] figure 1 It is a structural schematic diagram of an existing feedthrough current transformer. The principle of the feedthrough current transformer is based on the principle of electromagnetic induction and consists of a closed iron core and windings. As shown in the figure, in the prior art, a transformer body 1 is included, and the transformer body 1 has terminal posts 1.21, 1.22, and the terminal posts 1.21, 1.22 are connected to an ammeter. The transformer body 1 has a threading window 1.1, and the transformer body 1 is installed and fixed through the body fixing holes 1A and 1B. When installing the feed-through current transformer, pass the busbar 2 through the threading window 1.1, and the current value flowing through the busbar 2 can be read through the ammeter according to the principle of electromagnetic induction. However, when the existing through-type current transformer is disassembled and overhauled, since the threading window 1.1 is closed, the busbar n...

Abstract

In order to solve the problems existing in the prior art, a straight-through type current transformer with a movable opening comprises a transformer body, the transformer body is provided with a binding post and a threading window, the transformer body is installed and fixed through a body fixing hole, and the movable opening is formed in the body fixing hole. Due to the fact that the threading window of the current transformer is provided with the movable opening structure, when maintenance is needed, the transformer body can be moved away only by dismantling a pin shaft fixing bolt and enabling the rotating rod to rotate around the pin shaft to open one opening, a bus does not need to be dismantled in the whole process, and maintenance work is very convenient. And the problems in the prior art can be effectively solved.

Description

technical field [0001] The invention relates to a current detection device, in particular to a feed-through current transformer with movable openings. Background technique [0002] The principle of current transformer is based on the principle of electromagnetic induction and consists of a closed iron core and windings. There are many types of current transformers, among which the feedthrough current transformer is the most commonly used one. However, when the existing feedthrough current transformers are dismantled and overhauled, the busbar needs to be disassembled to remove them, which is very cumbersome. Contents of the invention [0003] In order to overcome the problems existing in the prior art, the present invention proposes a through-hole current transformer with movable openings. Since the threading window of the current transformer has a movable opening structure, when maintenance is required, only the pins need to be removed to fix it. Bolt, so that the rotati...
