Abstract
The invention discloses a combined circuit mutual inductor. The combined circuit mutual inductor is provided with a circuit board, a current transformer module and an electric leakage mutual inductor module, all of which are arranged sequentially from top to bottom, wherein the current transformer module is formed by combining and glue-filling a current transformer coil and a current transformer outer shell, and the electric leakage mutual inductor module is formed by combining and glue-filling an electric leakage manual inductor coil and an electric leakage mutual inductor outer shell. The combined circuit mutual inductor simplifies installation difficulty, fully utilizes universal rate of various mutual inductors, and highly integrates functions of the mutual inductor.
Description
Technical field
The present invention relates to a kind of instrument transformer, be specially a kind of combination transformer.
Background technology
The existing technical scheme in market be current transformer, creepage mutual inductor, power taking be all by independent connected mode to controller.
The shortcoming of prior art is: need to use a plurality of plugs at controller, can only use independent connecting line to be installed on switch inside, install cumbersome.
Summary of the invention
The defect that the present invention seeks to exist for prior art provides a kind of combinational circuit instrument transformer.
The present invention for achieving the above object, adopts following technical scheme:
A kind of combinational circuit instrument transformer of the present invention, it is characterized in that setting gradually wiring board, current transformer module and creepage mutual inductor module from top to bottom, described current transformer module forms after combining encapsulating by current mutual inductor coil and current transformer casing, and creepage mutual inductor module forms after combining encapsulating by creepage mutual inductor coil and creepage mutual inductor shell.
Preferably, described creepage mutual inductor enclosure arranges the copper bar button to external electricity.
The present invention has simplified the difficulty of installing, and takes full advantage of the general rate of various instrument transformers, Highgrade integration the function of instrument transformer.
Accompanying drawing explanation
Fig. 1: assembly drawing of the present invention.
