Description

A kind of current transformer device

Technical field

The utility model relates to a kind of current transformer device.

Background technology

Current transformer device is applied in transformer station usually for current conversion, in prior art, common current transformer device mainly contains two kinds: one is that current mutual inductor coil is integrated poured in current transformer housing, shown current transformer device cannot rotate, therefore, it cannot realize commutation; Another kind is that current mutual inductor coil assembling is fixed together with current transformer housing, when needing commutation, current mutual inductor coil assembling need be rotated together with current transformer housing simultaneously, its defect is: when the assembling of synchronous axial system coil is with housing, rotate comparatively difficulty, the rotating machinery used is comparatively complicated; Meanwhile, cause secondary connection plate in same transformer station on different current transformer device towards different, make wiring intricate, be even intertwined, affect attractive in appearance; When secondary connection plate go to upward position time, easily ponding in secondary connection plate, affects electric conductivity.

In view of the described defect of prior art current transformer device, the present inventor furthers investigate, and develop a kind of current transformer device overcoming described defect, this case produces thus.

Utility model content

The purpose of this utility model is to provide a kind of current transformer device, can partial turn current transformer device, makes commutation comparatively easy and convenient.

For reaching above-mentioned purpose, solution of the present utility model is:

A kind of current transformer device, comprises current transformer housing, commutation fishplate bar, current transformer body and secondary connection plate; Secondary connection plate is arranged on current transformer housing, is electrically connected with current transformer body; Commutation fishplate bar is pivotally arranged in current transformer housing, and current transformer body one end is fixedly mounted in current transformer housing, and when commutation Rotation With Changing phase fishplate bar is to correct position, the current transformer body other end is fixed on commutation fishplate bar.

Further, described commutation fishplate bar is rotatably arranged in current transformer housing by rotating shaft.

Further, described current transformer body comprises support tube, mutual inductor and supporting bracket; Supporting bracket is fixed in current transformer housing, and mutual inductor is arranged on support tube, and support tube one end is fixing on the supporting plate, and when commutation Rotation With Changing phase fishplate bar is to correct position, the support tube other end is fixedly mounted on commutation fishplate bar.

After adopting such scheme, the utility model commutation fishplate bar is pivotally arranged in current transformer housing, and current transformer body one end is fixedly mounted in current transformer housing, when commutation Rotation With Changing phase fishplate bar is to correct position, the current transformer body other end is fixed on commutation fishplate bar.Therefore, the utility model can partial turn commutation fishplate bar, and without the need to unitary rotation, makes commutation comparatively easy and convenient; Meanwhile, secondary connection plate maintains static without the need to synchronous axial system when commutation, makes secondary connection plate in same transformer station on different current transformer device towards unanimously, makes wiring regular, be unlikely to be intertwined, comparatively attractive in appearance; And secondary connection plate is unlikely to go to position upward, thus can not in secondary connection plate ponding and affect electric conductivity.

Embodiment

Below in conjunction with drawings and the specific embodiments, the utility model is described in detail.

Consult shown in Fig. 1 and Fig. 2, a kind of current transformer device that the utility model discloses, comprise current transformer housing 1, secondary connection plate 2, current transformer body 3 and commutation fishplate bar 4.

Secondary connection plate 2 is arranged on current transformer housing 1, is electrically connected with current transformer body 3.

Commutation fishplate bar 4 is pivotally arranged in current transformer housing 1, and current transformer body 3 one end is fixedly mounted in current transformer housing 1, during commutation Rotation With Changing phase fishplate bar 4 to correct position, current transformer body 3 other end is fixed on commutation fishplate bar 4.

As shown in Figure 2, described current transformer body 3 comprises support tube 31, mutual inductor 32 and supporting bracket 33.Supporting bracket 33 is fixed in current transformer housing 1, mutual inductor 32 is arranged on support tube 31 and also compresses with coil pressure plate 34, and support tube 31 one end is fixed in supporting bracket 33, during commutation Rotation With Changing phase fishplate bar 4 to correct position, support tube 31 other end is fixedly mounted on commutation fishplate bar 4.

Described commutation fishplate bar 4 is rotatably arranged in current transformer housing 1 by rotating shaft 5, is specially, and rotating shaft 5 one end is arranged in supporting bracket 33, and the other end is arranged on commutation fishplate bar 4.

The utility model is when non-commutation, and support tube 31 one end is socketed in supporting bracket 33, the other end by screw locking on commutation fishplate bar 4.During commutation, unclamp screw and commutation fishplate bar 4 is separated with support tube 31, Rotation With Changing phase fishplate bar 4 to correct position, then continuation screw is by the locking of support tube 31 other end on commutation fishplate bar 4, realizes commutation.

The utility model can partial turn commutation fishplate bar 4, and without the need to unitary rotation, makes commutation comparatively easy and convenient; Meanwhile, secondary connection plate 2 maintains static without the need to synchronous axial system when commutation, makes secondary connection plate 2 in same transformer station on different current transformer device towards unanimously, makes wiring regular, be unlikely to be intertwined, comparatively attractive in appearance; And secondary connection plate 2 is unlikely to go to position upward, thus can not in secondary connection plate 2 ponding and affect electric conductivity.

The foregoing is only preferred embodiment of the present utility model, not to the restriction of this case design, all equivalent variations done according to the design key of this case, all fall into the protection range of this case.
