Abstract
The utility model relates to a high-voltage isolation switch with good conductivity and aims at solving a technical problem that the existing isolation switch has low conductivity. The high-voltage isolation switch comprises a pedestal, a wire incoming insulation column, a wire outgoing insulation column, a wire incoming wiring board, a wire outgoing wiring board and a disconnecting link. The wire incoming insulation column and the wire outgoing insulation column are respectively fixed at two sides of the pedestal; the wire incoming wiring board is fixed on the wire incoming insulation column and the wire outgoing wiring board is fixed on the wire outgoing insulation column; and one end of the disconnecting link is hinged with the wire incoming wiring board and the other end thereof is contacted with the wire outgoing wiring boar well. According to the isolation switch, because the wiring boards are directly connected with the disconnecting link, the conductivity can be effectively improved and the production cost can be lowered. Moreover, the structure of the switch becomes simple.
Description
Technical field
The utility model relates to a kind of isolating switch, refers in particular to a kind of high voltage isolator of good conductivity.
Background technology
High voltage isolator is important device for switching in power plant and transformer station's electrical system, needs to support the use with primary cut-out, and its major function is: guarantee High-Voltage Electrical Appliances and the safety of device when service work, play isolation voltage.Be fixed with mounting panel on the insulated column of existing high voltage isolator, terminal block is fixed on mounting panel and with it and is electrically connected to, and therefore, terminal block is electrically connected to disconnecting link by mount pad, terminal block is not directly to be electrically connected to disconnecting link, thereby causes the problem that in use exists electric conductivity low.
Summary of the invention
In order to overcome deficiency and the defective in background technology, the utility model provides a kind of high voltage isolator of good conductivity, solves existing isolating switch and has the low technical problem of electric conductivity.
The technical solution of the utility model is: a kind of high voltage isolator of good conductivity, comprise base, inlet wire insulated column, outlet insulated column, inlet wire terminal block, outlet terminal block and disconnecting link, described inlet wire insulated column, outlet insulated column are individually fixed in the both sides of base, described inlet wire terminal block is fixed on the inlet wire insulated column, described outlet terminal block is fixed on the outlet insulated column, one end and the inlet wire terminal block of described disconnecting link are hinged, and the other end and outlet terminal block fit.
Described inlet wire insulated column, outlet insulated column all are fixed with two clamping plate, described two clamping plate are perpendicular to the end face of inlet wire insulated column, outlet insulated column, and described inlet wire insulated column and outlet insulated column are arranged in parallel, and described inlet wire terminal block, outlet terminal block all pass two clamping plate and be connected by securing member.
The end face of described inlet wire terminal block, outlet terminal block is arc.
The beneficial effects of the utility model: because the terminal block of this isolating switch directly is connected with disconnecting link, thereby effectively improve electric conductivity, reduced production cost, and structure is simpler.
Description of drawings
Fig. 1 is structural representation of the present utility model.
In figure, base 1, inlet wire insulated column 2, outlet insulated column 3, inlet wire terminal block 4, outlet terminal block 5, disconnecting link 6, clamping plate 7.
Embodiment
The below is described further embodiment of the present utility model for accompanying drawing:
As shown in the figure, a kind of high voltage isolator of good conductivity, comprise base 1, inlet wire insulated column 2, outlet insulated column 3, inlet wire terminal block 4, outlet terminal block 5 and disconnecting link 6, described inlet wire insulated column 2, outlet insulated column 3 are individually fixed in the both sides of base 1, described inlet wire terminal block 4 is fixed on inlet wire insulated column 2, described outlet terminal block 5 is fixed on outlet insulated column 3, and an end and the inlet wire terminal block 4 of described disconnecting link 6 are hinged, and the other end and outlet terminal block 5 fit.According to such scheme, because the terminal block of this isolating switch directly is connected with disconnecting link, thereby effectively improve electric conductivity, reduced production cost, and structure is simpler.
In the utility model, described inlet wire insulated column 2, outlet insulated column 3 all are fixed with two clamping plate 7, described two clamping plate 7 are perpendicular to the end face of inlet wire insulated column 2, outlet insulated column 3, and described inlet wire insulated column 2 and outlet insulated column 3 are arranged in parallel, and described inlet wire terminal block 4, outlet terminal block 5 all pass two clamping plate 7 and be connected by securing member.During installation, clamping plate 7 are fixed on insulated column, terminal block vertically passes two clamping plate 7, and is equipped with corresponding installing hole on clamping plate 7 and terminal block, and bolt passes installing hole and carries out fastening with nut.
In the utility model, the end face of described inlet wire terminal block 4, outlet terminal block 5 is arc, is conducive to improve smoothness.
Embodiment should not be considered as the restriction to utility model, but any improvement of doing based on spirit of the present utility model, all should be within protection range of the present utility model.
