Description
Technical field
The present invention relates to the power equipment switch, relate in particular to a kind of vacuum circuit-breaker isolation switch device.
Background technology
Development along with national economy, electric network composition and part throttle characteristics are day by day complicated, be connected to simultaneously the sensitiveness electric loading of electric power system, very easily be subject to the impact from electric power system disturbance in short-term, fall with voltage as voltage and jump, thereby for the quality of power supply and operational reliability, further strict requirement has been proposed, safety in order to ensure the ultra-high-tension power transmission line maintaining, the primary cut-out that is arranged on the outdoor high-voltage power transmission line is accompanied with isolating switch mostly, isolating switch and primary cut-out are connected in series, and are the important devices in electric power system.
General isolating switch is when operating grip divides, during closing operation, can make because the twisting resistance that bears is different the torsional deflection of operating grip, thereby make divide-shut brake not in place, and the stability of product is relatively poor, and operating efficiency is not high yet.
Summary of the invention
The technical problem to be solved in the present invention is: provide a kind of action stability good, reliable outdoor high-voltage vacuum circuit breaker isolating switch divides, closes a floodgate.
in order to overcome the defective that exists in background technology, the technical solution adopted for the present invention to solve the technical problems is: a kind of outdoor high-voltage vacuum breaker isolating switch, comprise quiet insulation column, insulated tension pole, moving insulation column, operating axis and operating grip, described quiet insulation column, insulated tension pole and moving insulation column are successively set on mounting panel, described quiet insulation column upper end is provided with static contact seat, described moving insulation column upper end is provided with moving contact seat, be provided with the isolation plug-in strip between described static contact seat and moving contact seat, described insulated tension pole connection plate and isolation plug-in strip, described operating grip attended operation axle.
According to another embodiment of the invention, be articulated and connected between described moving contact seat and isolation plug-in strip.
According to another embodiment of the invention, the mounting plane of the rotational plane of described isolation plug-in strip and quiet insulation column and moving insulation column overlaps.
According to another embodiment of the invention, described operating grip comprises separating brake draw ring and combined floodgate draw ring.
According to another embodiment of the invention, be flexible connection between described operating axis and operating grip.
According to another embodiment of the invention, described operating grip rotatablely moves around the operating axis axle center.
The invention solves the defective that exists in background technology, provide a kind of having stable behavior high, minute, the reliable outdoor high-voltage vacuum breaker isolating switch that closes a floodgate, improved security performance and electric conductivity in the circuit breaker course of work, applicable to high-current circuit.
Description of drawings
The present invention is further described below in conjunction with drawings and Examples.

Embodiment
The present invention is further detailed explanation with preferred embodiment by reference to the accompanying drawings now.These accompanying drawings are the schematic diagram of simplification, basic structure of the present invention only is described in a schematic way, so it only show the formation relevant with the present invention.
a kind of outdoor high-voltage vacuum breaker isolating switch as shown in Fig. 1-2, comprise quiet insulation column 1, insulated tension pole 2, moving insulation column 3, operating axis 4 and operating grip 5, described quiet insulation column 1, insulated tension pole 2 and moving insulation column 3 are successively set on mounting panel 6, described quiet insulation column 1 upper end is provided with static contact seat 7, described moving insulation column 3 upper ends are provided with moving contact seat 8, be provided with isolation plug-in strip 9 between described static contact seat 7 and moving contact seat 8, be articulated and connected between described moving contact seat 8 and isolation plug-in strip 9, described insulated tension pole 2 connection plates 6 and isolation plug-in strip 9, described operating grip 5 attended operation axles 4.
The rotational plane of the plug-in strip 9 of isolation described in the present invention and the mounting plane of quiet insulation column 1 and moving insulation column 3 overlap, namely isolate plug-in strip 9 at the installation of quiet insulation column 1 and moving insulation column 3 rotation with in surface of arranging, thereby realize separating and contacting between isolation plug-in strip 9 and static contact seat 7.
As shown in Figure 2, operating grip 5 in the present invention comprises separating brake draw ring 51 and combined floodgate draw ring 52, hook separating brake draw ring 51 and the combined floodgate draw ring 52 of operating grip and pull downwards with insulated operating rod, making isolation plug-in strip 9 separate with static contact seat 7 and contact, isolating switch can divide, closing operation.Operating grip 5 attended operation axles 4, between operating axis 4 and operating grip 5, for being flexibly connected, in practical work process, operating grip 5 rotates around operating axis 4 axle center
operation principle of the present invention is: when automatic circuit is in open position, isolating switch divides, closing operation, operating grip 5 is applied external force, separating brake draw ring 51 and the combined floodgate draw ring 52 of noting two ends on operating grip 5 divide downwards, the direction of arrow of closing, hook separating brake draw ring 51 and the combined floodgate draw ring 52 on operating grip and pull downwards with insulated operating rod, make isolation plug-in strip 9 separate with static contact seat 7 and contact, isolating switch can divide, closing operation, pull speed should be as far as possible fast (pull down power must greater than 40kg) downwards, to guarantee that isolating switch divides, closing operation has certain speed and impulsive force.
Take above-mentioned foundation desirable embodiment of the present invention as enlightenment, by above-mentioned description, the relevant staff can in the scope that does not depart from this invention technological thought, carry out various change and modification fully.The technical scope of this invention is not limited to the content on specification, must determine its technical scope according to the claim scope.
