Description
Technical field
The present invention relates to a kind of bracing or strutting arrangement, particularly relate to a kind of by the device of the current transformer fixed support of bus, belong to equipment for power transmission and distribution technical field.
Background technology
Busbar current transformer is circulus, and it is sleeved in bus, and bus-bars conductor passes from its inner ring, and bus shell around its outer ring, then needs current transformer to be fixedly supported in bus.Current transformer body cylindrical is embedded with screwed hole, traditional mounting means is through bolt in the outside of bus shell, the screwed hole of align currents instrument transformer cylindrical by fixing, but owing to there is certain spacing between current transformer and bus shell, need the position of constantly adjustment current transformer, therefore be difficult to aim at screwed hole, once there is deviation, then directly can damage current transformer in junction, be difficult to operation, and easily there is accident, take time and effort.
Summary of the invention
The object of the present invention is to provide a kind of bracing or strutting arrangement of busbar current transformer, this device can fixed current instrument transformer fast and effectively, and can guarantee the safety of current transformer.
The present invention is achieved by the following technical programs:
A bracing or strutting arrangement for busbar current transformer, comprises stopping means, fixture, and stopping means and fixture are arranged along current transformer radial symmetric, stopping means comprises guide vane end stop, separation pad one, and a side of guide vane end stop is welded on the medial surface of bus shell, fixture comprises separation pad two, mount pad, sealing gasket, sealing shroud, separation pad one and separation pad two are cuboid part, one side is equipped with groove, separation pad one and separation pad two to be all arranged between current transformer and bus shell and the relative thickness direction being connected to current transformer of its groove, separation pad one is resisted against on the another side of guide vane end stop, the groove back side of separation pad two is provided with several screwed hole, mount pad is ladder axial workpiece and is provided with a through hole, mount pad to be passed from the lateral surface of bus shell by its small end and is resisted against the back side of separation pad two, sealing gasket seals up the through hole of mount pad, sealing shroud entangles sealing gasket, bolt is through sealing shroud, mount pad is also connected with the screwed hole at separation pad two back side.
The present invention can also realize by the following technical programs further.
The bracing or strutting arrangement of aforesaid a kind of busbar current transformer, is provided with number cover stopping means and fixture along current transformer axis and radial direction.
The present invention fixes current transformer by symmetrically arranged stopping means and fixture, separation pad one clamping steadily can live current transformer with the groove of separation pad two, safe and reliable, be connected by the screwed hole of bolt with separation pad two back side, continuous screwing bolts, bolt pushes mount pad and is tightly resisted against on current transformer by separation pad two, this device only needs the screwed hole of separation pad two to aim at the hole of bus shell, do not need the screwed hole making Current Transformer cylindrical, therefore current transformer can arbitrarily be placed in bus, do not need the position adjusting current transformer, it is quick that operation is very easy, to save time and manually, also can guarantee being perfectly safe of current transformer, and installation and maintenance are convenient.
Advantage and disadvantage of the present invention, by for illustration and explanation for the non-limitative illustration passing through preferred embodiment below, these embodiments, only provide as an example with reference to accompanying drawing.
