Abstract

The utility model belongs to electric devices, particularly relates to an open-close type current transformer. The close type current transformer comprises two semi-circle annular transformer bodies, stainless steel ferrules holding tightly the two semi-circle rings, iron cores inside the transformer bodies and resin outer shell at the outer layer, wherein the outer layers of the two semi-circle rings are provided with stainless steel ferrule clamping grooves, one end of each stainless steel ferrule is a bolt tension terminal, the other end of a steel tape penetrates the bolt tension terminal, the outer layers of the two semi-circle rings are respectively provided with at least one stainless steel ferrule fixing block, strip-shaped penetrating holes are formed by the fixing blocks and the clamping grooves, and the number of the stainless steel ferrules and the stainless steel ferrule clamping grooves are two or more. According to the pen-close type current transformer, the design of the stainless steel ferrule clamping grooves enables the installation of the open-close type current transformer to be convenient and operation to be simple and convenient. An adjustable stainless steel belt enables the iron cores of the transformer to be attached tightly and magnetic conductivity to be high, and is small in size, light in weight and capable of being opened. In the process of installation, the two semi-circle rings are clamped on a cable, the stainless steel ferrules are used to hold the two semi-circle rings tightly, and therefore the open-close type current transformer can be integrated with the cable, and harmony and beauty are achieved.

Description

Open-close type current transformer

Technical field

The utility model belongs to electric device, particularly a kind of open-close type current transformer.

Background technology

Present common open-close type current transformer; Mostly be that two semicircular ring are formed, during use two parts be buckled on the circuit, with circles such as stainless steel band, plastic tape hoop two parts are fixed together then; And in fact in the operating process; Because technical problem, two opened and involutoryly to drop easily in half minute, installed inconvenient.

Summary of the invention

The purpose of the utility model is to avoid the weak point of above-mentioned prior art, and a kind of open-close type current transformer of safe and reliable convenient installation and operation is provided.

Technical scheme:

A kind of open-close type current transformer; Comprise two semi-round ring shape current transformer body, hold the stainless steel stirrup of two semicircular ring tightly, the inner iron core of current transformer body; Skin is a resin enclosure; Described two semicircular ring skins are provided with stainless steel stirrup draw-in groove, and stainless steel stirrup one end is a bolt tension terminal, and other end steel band passes from bolt tension terminal.

Described two semicircular ring skins are at least respectively established 1 stainless stirrup fixed block, and fixed block and draw-in groove constitute the strip perforation.

Described stainless steel stirrup and draw-in groove thereof are two or many.

The beneficial effect of the utility model:

1, the open-close type current transformer of the utility model, the design of stainless steel stirrup draw-in groove is convenient to install involutory instrument transformer, and is easy and simple to handle, and it is tightr that adjustable stainless steel band can make transformer iron core fit, and magnetic conductivity is higher.

2, the open-close type current transformer of the utility model, volume is little, and is in light weight, can open, and during installation two semicircular ring is stuck on the cable, holds tightly with the stainless steel stirrup, combines together with cable, harmonious attractive in appearance.
