Abstract
A current transformer relates to the field of low-voltage apparatus and comprises a shell, a containing cavity is formed inside the shell, a coil is disposed inside the containing cavity, an electronic circuit board electrically connected with the coil and provided with a rectifier circuit is further mounted in the containing cavity, and a socket is mounted on the electronic circuit board. By adopting the technical scheme, the current transformer without outgoing lines is convenient in mounting during production or change in after-sale service, rejection of the whole current transformer due to damage of the outgoing lines of the current transformer is avoided, and cost consumption in production is reduced. The rectifier circuit is disposed inside the current transformer, so that energy signals of the current transformer are outputted as pulse signals, size of an intelligent controller is reduced, and implementation of miniature of the intelligent controller is benefited.
Description
Technical field
The utility model relates to a kind of current transformer, belongs to the low-voltage electrical apparatus field.
Background technology
The lead-out wire of existing circuit breaker Current Transformer directly is connected to intelligent controller, misoperation or the current transformer lead-out wire that causes lack of standardization is installed is damaged in the circuit breaker production process, this current transformer just can't continue to use so, must dismantle circuit breaker again and new current transformer is installed, increase production cost thus, locate the user, if the current transformer of circuit breaker breaks down, the on-the-spot very trouble of changing of after-sale service personnel, except needs from circuit breaker rear dismounting current transformer, also need from parts such as circuit breaker the place ahead dismounting intelligent controllers.And the structure of present current transformer is not suitable for the requirement of current circuit breaker miniaturization.
Summary of the invention
The utility model is to overcome the deficiencies in the prior art, provides a kind of and can make the circuit breaker miniaturization, and change simply the current transformer that reduces production costs.
The utility model is achieved through the following technical solutions: a kind of current transformer, comprise shell, described enclosure forms a cavity volume, the inner coil of placing of described cavity volume, the electronic circuit board that is electrically connected with coil also is installed in the described cavity volume, described electronic circuit board is provided with socket, and this socket is used to connect the current transformer lead-out wire.
Also have a rectification circuit on the described electronic circuit board, the input of described rectification circuit is connected with coil, and the output of described rectification circuit is connected with socket.
Described shell is fastened and connected and is formed by first housing, second housing.
Described first housing offers a groove.
Be equipped with two draw-in grooves that electronic circuit board is installed in the described groove.
Also offer the cavity that holds socket on the described groove.
The present invention adopts technique scheme, compared with prior art has following advantage:
The utility model is owing to adopt technique scheme, current transformer does not have lead-out wire, in the production process or after-sale service easy for installation when changing, avoid because the damage of current transformer lead-out wire causes whole current transformer to be scrapped cost depletions in the reduction production process.Rectification circuit is built in the current transformer, makes the current transformer energy signal be output as fluctuating signal, has saved the volume of intelligent controller, helps intelligent controller and realizes miniaturization.
