Description
Technical field
The utility model relates to panel switches field, particularly a kind of miniaturized integrated solid insulation isolating switch.
Background technology
Traditional solid insulation isolating switch comprises isolation knife, fixed contact, it is inner that they and vacuum tube etc. are arranged on solid insulation device, simultaneously the top of solid insulation device or bottom are furnished with inlet wire or outlet casing tube, to be connected with bus or cable, therefore realize single grounding or outlet ground connection only.By the combined floodgate deciliter realizing major loop and the ground connection operation of isolation knife.Due to the many limited spaces of seal body interior parts, electric insulation distance is restricted, and this mode increases the volume of solid insulation device body undoubtedly, adds installation difficulty simultaneously, and is not easy to operation, comparatively requires great effort.Simultaneously when major loop combined floodgate or ground connection, junction, moved end or the grounding static contact junction of the metal fittings such as isolation knife and vacuum tube are connected, easily occur that the influence each other Electric Field Distribution that causes of two conductors is uneven same seal is inner, the phenomenons such as local field strength increase, increase the danger coefficient of surrounding environment.
Summary of the invention
For solving the problem, the purpose of this utility model is to provide a kind of miniaturized integrated solid insulation isolating switch, Miniaturization Design, and realization isolation is integrated with earthed switch, directly increases the useful life of product, reduces operating physical force during switching manipulation.
The technical scheme that the invention for solving the technical problem adopts is:
A kind of miniaturized integrated solid insulation isolating switch, comprise insulating cylinder, described insulating cylinder inside is provided with isolation contact arm assembly, the bottom of described isolation contact arm assembly is connected with isolation fixed contact, the top of described isolation contact arm assembly is connected with isolation drive plate, the top of described isolation contact arm assembly is also set with grounding contact seat, and described isolation drive plate top is connected contact with being provided with between bottom.
Further, described connection contact inside is provided with fingertip spring, and described connection contact is connected with isolation contact arm assembly by fingertip spring.
Further, the top of described insulating cylinder is provided with sealing baffle, is connected after the through sealing baffle in top of described isolation contact arm assembly with isolation drive plate.
Further, described insulating cylinder inside is provided with support platform, and described connection contact is provided with the outer projection of movement corresponding with support platform.
The beneficial effects of the utility model are:
The utility model adopts a kind of miniaturized integrated solid insulation isolating switch, isolating switch main body is three-phase independent split type, be arranged on the split of solid insulation three-phase independently in insulating cylinder, the transmission of isolating switch is three-phase synchronous action, and realization isolation is closed, isolation divides, isolate ground connection three station manipulation; The utility model realization isolation is integrated with earthed switch, without the need to dropping into an earthed switch more in addition; Independently isolating switch body is less for three-phase, really achieves miniaturization.
Accompanying drawing explanation
Below in conjunction with accompanying drawing and example, the utility model is described in further detail.
Fig. 1 is overall structure schematic diagram of the present utility model;
Fig. 2 is the schematic diagram that the utility model isolation divides;
Fig. 3 is the schematic diagram that the utility model ground connection is closed.
Embodiment
Shown in Fig. 3, preferred embodiment of the present utility model provides a kind of miniaturized integrated solid insulation isolating switch, comprise insulating cylinder 1, described insulating cylinder 1 inside is provided with isolation contact arm assembly 2, the bottom of described isolation contact arm assembly 2 is connected with isolation fixed contact 3, the top of described isolation contact arm assembly 2 is connected with isolation drive plate 4, and the top of described isolation contact arm assembly 2 is also set with grounding contact seat 5, and described isolation drive plate 4 top is connected contact 6 with being provided with between bottom.
The top of described insulating cylinder 1 is provided with sealing baffle 8, is connected after the through sealing baffle 8 in top of described isolation contact arm assembly 2 with isolation drive plate 4.
Described insulating cylinder 1 inside is provided with support platform 9, and described connection contact 6 is provided with the outer projection 10 of movement corresponding with support platform 9.
From above structure, isolating switch main body is three-phase independent split type, and be arranged on the split of solid insulation three-phase independently in insulating cylinder 1, the transmission of isolating switch is three-phase synchronous action, thus achieve that isolation is closed, isolation point, isolation ground connection three station manipulation.
Connecting contact 6 and the frictional force of isolation contact arm assembly 2 to reduce, reducing wearing and tearing between the two, reducing the resistance brought because himself plated surface silver layer reduces and increase impact, in connection contact 6, fingertip spring 7 is installed.Therefore, in the middle of whole switch, connecting contact 6 is fixed in insulating cylinder 1, isolation contact arm assembly 2 is by connecting fingertip spring 7 on contact 6 and being connected contact 6 and connecting, which solve the problem connecting contact 6 melting welding, directly increase the useful life connecting contact 6, and operating physical force when decreasing switching manipulation.
With reference to shown in Fig. 2, for isolating switch isolates the schematic diagram after dividing.With reference to shown in Fig. 3, it is the schematic diagram after the conjunction of isolating switch ground connection.Known with reference to Fig. 2 and Fig. 3, when isolation contact arm assembly 2 slides up and down, isolation fixed contact 3 and grounding contact seat 5 correspondence realize the electrical connection of isolation and ground connection, and what realize isolating with earthed switch is integrated, need not drop into an earthed switch in addition again.
Isolation fixed contact 3 of the present utility model, connection contact 6 all use uniform electric field process, product point discharge when avoiding switch to be energized.
Three-phase independent isolating switch of the present utility model is less, and total height is 530mm only, single-phase width only 40mm, and be contained on solid insulation switch, spaced apart only needs 100mm, can realize real miniaturization.
The above, just preferred embodiment of the present utility model, the utility model is not limited to above-mentioned execution mode, as long as it reaches technique effect of the present utility model with identical means, all should belong to protection range of the present utility model.
