Abstract
The utility model relates to a heavy-current isolation mechanism for a high-voltage cabinet, which comprises a frame, wherein a support base is arranged on the frame; two rows of insulators which are opposite up and down are arranged on the support base; the insulators are provided with a moving contact matched with a fixed contact in the high-voltage cabinet; and the moving contacts opposite up and down are connected integrally through a conducting plate so as to form a moving contact conducting channel. The heavy-current isolation mechanism has the advantages of simple structure, convenient operation, reliable use, low cost, reasonable design, and capability of being mounted in the high-voltage cabinet so as to save cost.
Description
Technical field
The utility model relates to the big electric current interrupter that uses in a kind of electric power system high-voltage board.
Background technology
In electric power system; be used for the operating disconnection of 10KV electric substation high-tension line and isolate employing circuit breaker realization usually; because circuit breaker mainly acts on to be carrying and to disconnect the electric current in unusual loop and carry out decompression, under-voltage, overload and short-circuit protection automatically; so its structure more complicated; cost is higher; this multi-functional parts only are used for the single electric current of high-voltage board and disconnect isolation, itself also are a kind of wastings of resources.
Summary of the invention
The purpose of this utility model is to provide the big electric current interrupter of high-voltage board a kind of simple in structure, safe and reliable.
Technical solution of the present utility model is: the big electric current interrupter of a kind of high-voltage board, comprise: vehicle frame, it is characterized in that on vehicle frame, being provided with supporting base, the insulator that two rows are oppositely arranged up and down is installed on the supporting base, insulator is provided with the moving contact that matches with fixed contact in the high-voltage board, the moving contact that is oppositely arranged up and down fuses by conductive plate, forms moving contact electric pathway up and down.
The big electric current interrupter of the high-voltage board that the utility model provides, by mobile vehicle frame, moving contact on the interrupter and the fixed contact in the high-voltage board can be combined into one, form the unimpeded loop of electric substation's high-tension electricity conveying circuit, perhaps moving contact is separated with fixed contact, disconnect conveying circuit.
Characteristics of the present utility model are: simple in structure, easy to operate, safe and reliable, cost is low, and is reasonable in design, can be installed in the existing high-voltage board, saves cost.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the end view of Fig. 1.
Embodiment
The utility model is described in further detail below in conjunction with accompanying drawing:
As shown in Figure 1, 2, the both sides of frame chassis 1 of the present utility model are provided with wheel 7, and the bottom on chassis is provided with and drives the transmission mechanism that vehicle frame moves, and is connected and composed by parts such as hand cranking handle 8, leading screws, and not shown leading screw is not limited thereto transmission mechanism.Be fixed with vehicle frame 2 on the chassis, be installed with supporting base 3 on the vehicle frame, be fixed with the two row's insulators 4 that are oppositely arranged up and down on the supporting base, each row is provided with 3 insulators of arranging at a certain distance, be fixedly connected with moving contact 6 on the insulator, be that copper coin 5 connects by conductive plate between the moving contact on the relative up and down insulator, form electric pathway.Insulator also is used to form certain insulation distance when playing the effect of support electrified body, guarantee the insulation of high-voltage board.
The big electric current interrupter of high-voltage board is mounted in the high-voltage board, and its moving contact is a high-voltage plug with fixed contact in the high-voltage board is that high-tension terminal matches.When keeping electric substation's high-tension line to be in "on" position, three-phase current is gone up loop inflow and the outflow that dynamic/static contact, conductive plate and following dynamic/static contact form respectively by combining.When circuit is in power down mode, in the time of the turnover circuit need being disconnected,, leading screw is rotated by shaking handle, drive frame chassis and outside cabinet, move, upper and lower dynamic/static contact is separated, circuit disconnects.
