Abstract
The utility model discloses an LMZ bus type current transformer. The LMZ bus type transformer comprises two semi-ring current transformer units, one end of the semi-ring current transformer unit is hinged with one end of the other semi-ring current transformer unit, the other end of one semi-ring current transformer unit is buckled with the other end of the other semi-ring current transformer unit. Both the semi-ring current transformer units are formed by coils, when the two semi-ring current transformer units are buckled together, a coil winding is formed. According to the LMZ bus type current transformer, when line loss is detected, power needs not to be cut off, the LMZ bus type current transformer can be detached and electrical loss of the transformer is detected just opening a snap ring (6).
Description
Technical field
The utility model relates to a kind of LMZ bus type current transformer.
Background technology
The LMZ bus is bus commonly used in the electric power, and current transformer is through on the LMZ bus usually, for detection of the state measurement of LMZ bus.Because the current transformer of existing market adopts closed type mostly, so when measuring, bus need be had a power failure, and then current transformer is pulled down taking-up, cause the reliability of power supply relatively poor, and each dismounting inconvenience, greatly reduce operating efficiency.
Summary of the invention
The utility model proposes a kind of LMZ bus type current transformer at the problem that prior art exists, and it comprises two semi-round ring shape current transformer unit, and an end of two semi-round ring shape current transformer unit is hinged, and the other end snaps together; Each semi-round ring shape current transformer unit constitutes by coil, when two semi-round ring shape current transformer unit snap together, forms coil windings.
Two semi-round ring shape current transformer unit one ends snap together and refer to: the buckling end of two semi-round ring shape current transformer unit is zigzag fashion, and the buckling end of two zigzag fashions is interlocked.
Two semi-round ring shape current transformer unit one ends snap together and refer to: between two semi-round ring shape current transformer unit connector is set.
Each semi-round ring shape current transformer unit skin is provided with insulating barrier.
By improvement of the technical scheme, the utility model has following advantage: do not need when detecting the line loss problem to have a power failure and current transformer can be pulled down, installation and removal are convenient; The buckling end of two semi-round ring shape current transformer unit is zigzag fashion, fastens closely, has strengthened the conductive capability of current transformer; Be convenient to make, implement easily, be easy to penetration and promotion.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Embodiment
Below in conjunction with accompanying drawing the utility model is done and to be described in further detail.
As shown in Figure 1, the utility model comprises semi-round ring shape current transformer unit I1 and semi-round ring shape current transformer unit II2, and the end of semi-round ring shape current transformer unit I1 and semi-round ring shape current transformer unit II2 is articulated in pin joint 3; Other end junction at semi-round ring shape current transformer unit I1 and semi-round ring shape current transformer unit II2 arranges connector 4 and connector 5, connector 4 is fixed on the semi-round ring shape current transformer unit I1, connector 5 is fixed on the semi-round ring shape current transformer unit II2, and semi-round ring shape current transformer unit I1 is connected by buckle 6 with the other end of semi-round ring shape current transformer unit II2; Each semi-round ring shape current transformer unit constitutes by coil, when two semi-round ring shape current transformer unit snap together, forms coil windings.When detecting the line loss problem, need not to have a power failure, only need open buckle 6, the dismounting of LMZ bus type current transformer can be carried out the electricity damage and is detected.
