Abstract
The utility model relates to a simple disconnecting switch which comprises a pedestal. The pedestal is provided with several fixed contacts, several cutter-bearing moving contacts and several limited rods. Several knobs are installed on the pedestal. The fixed contacts are uniformly distributed on the pedestal. The bottom of each knob is provided with a bump which has an elliptical shape. The bump is provided with a limit slot. According to the utility model, one knob can control load circuits of two loops, and also can individually control one loop. In addition, the simple disconnecting switch is simple and convenient to operate and is economical and practical.
Description
Technical field
The utility model relates to a kind of switch, relates in particular to a kind of simple and easy isolating switch.
Background technology
In power engineering, isolating switch is one of conventional electric component, after isolating switch separating brake, sets up reliable clearance for insulation, and the equipment that needs are overhauled or circuit and power supply separate with an obvious cut-off point, to ensure the safety of maintainer and equipment.In addition, isolating switch is according to operation needs, changing-over circuit, also can be used to point, little electric current in zygonema road, as the charging current of sleeve pipe, bus, connector, stub cable, the capacitance current of switch equalizing capacitance, circulation when double-bus changing-over and the exciting current of voltage transformer etc., can also be according to the concrete condition of different types of structure, can be used to point, the open-circuit excitation electric current of unification constant volume transformer.But existing high-power isolating switch, if control the load circuit in one or more loop simultaneously, just needs different isolating switches, takes up room large, when installation fee, cost is higher.
Utility model content
The purpose of this utility model is in order to overcome the deficiencies in the prior art, and a kind of simple and easy isolating switch is provided.
The utility model is to be achieved through the following technical solutions:
A kind of simple and easy isolating switch, comprises pedestal, and described pedestal is provided with some fixed contacts, several band cutter moving contacts, several gag lever posts, and several knobs are installed on pedestal, and the bottom of described knob is provided with projection, and described projection is provided with stopper slot; The fixed contact, band cutter moving contact, gag lever post and the knob that on described pedestal, arrange can be designed as comparatively reasonably number according to the actual requirements, because the demand of different environments for use, the number of respective design can just not done concrete restriction at this according to actual requirement design.
As optimal technical scheme of the present utility model, described fixed contact is evenly distributed on pedestal.
As optimal technical scheme of the present utility model, described projection shape ovalize.
When on-the-spot use, the utility model is arranged on correct position by operating personnel, single loop can be arranged on the knob at two ends of pedestal, then two loops are arranged on the knob of pedestal middle-end, like this, the utility model can be controlled the load circuit in one or two loop simultaneously.
Compared with prior art, the beneficial effects of the utility model are: knob of the utility model can be controlled the load circuit in two loops, also can control separately a loop, and simple to operation, economical and practical.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
Embodiment
In order to make the purpose of this utility model, technical scheme and advantage clearer, below in conjunction with drawings and Examples, the utility model is further elaborated.Should be appreciated that specific embodiment described herein is only in order to explain the utility model, and be not used in restriction the utility model.
Refer to Fig. 1, Fig. 1 is structural representation of the present utility model.
The simple and easy isolating switch of described one, comprise pedestal 1, described pedestal 1 is provided with some fixed contacts 2, several band cutter moving contacts 3, several gag lever posts 4, gag lever post 4 contributes to the position of the rotation that limits knob 5, described fixed contact 2 is evenly distributed on pedestal 1, several knobs 5 are installed on pedestal 1, the bottom of described knob 5 is provided with projection 51, described projection 51 shape ovalizes, projection 51 is provided with stopper slot 511, projection 51 can make to produce distortion with the blade on cutter moving contact 3, makes to be with cutter moving contact 3 to contact with fixed contact 2.
When on-the-spot use, the utility model is arranged on correct position by operating personnel, single loop can be arranged on the knob 5 at two ends of pedestal 1, then two loops be arranged on the knob 5 of pedestal 1 middle-end, like this, the utility model can be controlled the load circuit in one or two loop simultaneously.
The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all any amendments of doing within spirit of the present utility model and principle, be equal to and replace and improvement etc., within all should being included in protection range of the present utility model.
