Abstract

The utility model relates to a two switching of power mechanisms of high pressure, its characterized in that: including the frame, establish in the frame the removal rack and with the gear that removes rack toothing, the gear is driven by the motor, removal rack both ends are internal to be equipped with the slide and to establish the slide bar in the slide, the slide bottom is equipped with the metal contact, the utility model discloses two switching of power mechanisms of high pressure simple structure, reasonable in design are favorable to reduce cost.

Description

High-voltage dual power switching mechanism
technical field:
The utility model relates to a kind of high-voltage dual power switching mechanism.
background technology:
High-voltage dual power refers to the twin-power switch being applied to high pressure occasion, generally includes high-pressure vacuum breaker.When conventional power failure has a power failure, switching device shifter can complete the switching with stand-by power supply, to ensure reliability and fail safe.Also can switch according to the selection carried out between two-way power supply that needs of load.
But the switching mechanism of current high-voltage dual power, has two kinds of modes usually, and a kind of is manual, and danger is larger, and another has been come by intelligent operation/cutting mechanism, but this mechanism, and consume energy high, complex structure volume is large, and maintenance cost is high.
summary of the invention:
The purpose of this utility model is to provide a kind of high-voltage dual power switching mechanism, and this high-voltage dual power switching mechanism structure is simple, reasonable in design, is conducive to reducing costs.
The utility model high-voltage dual power switching mechanism, it is characterized in that: comprise frame, the mobile rack be located in frame, and with mobile rack meshed gears, described gear is by driven by motor, be provided with slideway in the body of described mobile rack two ends and be located at the sliding bar in slideway, bottom described slideway, be provided with hard contact.
Further, above-mentioned hard contact periphery is coated with insulating ceramics.
Further, above-mentioned hard contact is electrically connected with electrical equipment.
Further, above-mentioned frame both sides are respectively equipped with single power supply trigger end.
Further, above-mentioned two sliding bars are equipped with two flanges, described slideway inner port is provided with the inward flange that limit slippage bar is deviate from.
The operation principle of the utility model high-voltage dual power switching mechanism, when not working, tooth bar is positioned at centre position, all connect less than the single power supply trigger end with frame both sides, and at needs with when wherein a kind of power supply trigger end is connected, as long as starter motor, driven gear drives tooth bar to move, after tooth bar moves into place, the first sliding bar end on tooth bar and the power supply trigger end of first end are connected, the first hard contact be simultaneously provided with bottom slideway is also communicated with the first sliding bar end, thus being communicated with of connection first end power supply and electrical equipment; When needs connection second end power supply, reverse starting motor, motor driven gear drives tooth bar oppositely movement, when tooth bar moves to the other end, first sliding bar departs from the connection with first end power supply trigger end, and the power supply trigger end of the second sliding bar end on tooth bar and the second end is connected, the second hard contact be simultaneously provided with bottom slideway is also communicated with the second sliding bar end, thus connects being communicated with of this second end power supply and electrical equipment; When there is sliding bar stuck phenomenon, also disconnecting because the disengaging of tooth bar inner slide bottom metal contact contacts with sliding bar, thus avoiding phenomenon occurs to get an electric shock safely.
The utility model high-voltage dual power switching mechanism not only structure is simple, reasonable in design, and is conducive to avoiding the electric shock when there is stuck phenomenon.
accompanying drawing illustrates:
Fig. 1 is organigram of the present utility model.
embodiment:
Below in conjunction with accompanying drawing and actual execution mode, the utility model is described in further detail.
The utility model high-voltage dual power switching mechanism, comprise frame 1, the mobile rack 2 be located in frame 1, and with mobile rack 2 meshed gears 3, described gear 3 is by driven by motor, the sliding bar 6 being provided with slideway 5 in the body of described mobile rack 2 two ends and being located in slideway 5, is provided with hard contact 7 bottom described slideway.
Further, in order to play good insulation, above-mentioned hard contact periphery is coated with insulating ceramics 8.
Further, above-mentioned hard contact is electrically connected with electrical equipment, and this electrical equipment can be the bus of commercial power.
Further, above-mentioned frame both sides are respectively equipped with single power supply trigger end, and power supply can be that generator exports electricity or civil power.
Further, in order to reasonable in design, above-mentioned two sliding bars are equipped with two flanges 9, described slideway inner port is provided with the inward flange 10 that limit slippage bar is deviate from, first flange 901 is located at bottom sliding bar, and the second flange 902 is located at sliding bar stage casing, and inward flange 10 effect is that spacing second flange is deviate from.
The operation principle of the utility model high-voltage dual power switching mechanism, when not working, tooth bar is positioned at centre position, all connect less than the single power supply trigger end with frame both sides, and at needs with when wherein a kind of power supply trigger end is connected, as long as starter motor, driven gear drives tooth bar to move, after tooth bar moves into place, the first sliding bar end on tooth bar and the power supply trigger end of first end are connected, the first hard contact be simultaneously provided with bottom slideway is also communicated with the first sliding bar end, thus being communicated with of connection first end power supply and electrical equipment; When needs connection second end power supply, reverse starting motor, motor driven gear drives tooth bar oppositely movement, when tooth bar moves to the other end, first sliding bar departs from the connection with first end power supply trigger end, and the power supply trigger end of the second sliding bar end on tooth bar and the second end is connected, the second hard contact be simultaneously provided with bottom slideway is also communicated with the second sliding bar end, thus connects being communicated with of this second end power supply and electrical equipment; When there is sliding bar stuck phenomenon, also disconnecting because the disengaging of tooth bar inner slide bottom metal contact contacts with sliding bar, thus avoiding phenomenon occurs to get an electric shock safely.
The utility model high-voltage dual power switching mechanism not only structure is simple, reasonable in design, and is conducive to avoiding the electric shock when there is stuck phenomenon.
The foregoing is only preferred embodiment of the present utility model, all according to the utility model claim accomplish change with modify all should belong to covering scope of the present utility model.
