Abstract
The utility model relates to an isolating switch anti-misoperation device which is arranged between a bypass isolating switch and a line isolating switch. The isolating switch anti-misoperation device includes a mechanical linkage disc, a linkage fixing member, a horizontal transmission connecting rod, a limiting baffle plate, a grounding switch locking baffle plate, and connecting rod fixing frames. The mechanical linkage disc is fixed on the upper end of a transmission connecting rod of the bypass isolating switch, and is connected with one end of the horizontal transmission connecting rod via the linkage fixing member. A pedestal of the bypass isolating switch and a pedestal of the line isolating switch are provided with the connecting rod fixing frames which can support the horizontal transmission connecting rod. One side of the horizontal transmission connecting rod close to the line isolating switch is provided with the limiting baffle plate. When the bypass isolating switch is in the switching-on position, the limiting baffle plate is arranged on the grounding switch locking baffle plate which is arranged on a line side grounding switch transmission shaft. The isolating switch anti-misoperation device realizes the mechanical locking relation between the bypass insolating switch and the line side grounding switch of the line isolating switch in a same interval, and avoids the accidents caused by the hot-line grounding switch false switching-on in sideband operation.

Technical field
The utility model relates to the field of switches that electric power system is used, and particularly relates to the isolating switch anti-misoperation apparatus that a kind of power system transformer substation uses.
Background technology
In electric power system at present, the transformer station of many atypia designs is arranged, exist other female connection type., operational mode high because of its power supply reliability is used widely flexibly.In the transformer station that other female wiring is arranged, exist bypass isolating switch for the typical operation of line disconnecting switch operation.In this generic operation, when line disconnecting switch transfers inspecting state to, may occur because of certain reason, cause the line side earthed switch of zygonema road isolating switch by mistake, thereby lead to misoperation fault.
The utility model content
The purpose of this utility model is exactly by providing a kind of isolating switch anti-misoperation apparatus, make between the bypass isolating switch at the line side earthed switch of line disconnecting switch and same interval and form the mechanical latching relation, thoroughly stop in the sideband operation accident of charged mistake zygonema trackside earthed switch.
To achieve these goals, the utility model has adopted following technical scheme:
A kind of isolating switch anti-misoperation apparatus is arranged between bypass isolating switch, line disconnecting switch, it is characterized in that: comprise mechanical linkage dish, interlock firmware, horizontal kinematic link, postive stop baffle, cutter latch-down baffle and connecting rod fixed mount.
Described mechanical linkage dish is fixedly mounted on the upper end of the kinematic link of bypass isolating switch, is designed with installing hole on the mechanical linkage dish, is fixedly connected with an end of horizontal kinematic link by the interlock firmware; On bypass isolating switch and line disconnecting switch pedestal channel-section steel, each installs a connecting rod fixed mount, and horizontal kinematic link therefrom passes, and is used for placement and the support of horizontal kinematic link; Near a side of line disconnecting switch, postive stop baffle is installed on horizontal kinematic link, during at closing position, postive stop baffle is positioned at the cutter latch-down baffle place, ground that is arranged on the earthed switch power transmission shaft of line side when bypass isolating switch.
Can design a plurality of installing holes on the interlock dish, for adapting to the dissimilar isolating switch in job site, by selecting different installing holes, regulate the position of horizontal kinematic link other end postive stop baffle.
Horizontal kinematic link can be designed to adjustable lever, to adapt to the requirement of different installing spaces.
Offer the waist circular port on the connecting rod fixed mount, the requirement that moves forward and backward to satisfy horizontal kinematic link.
During use, utilize the rotation of deciliter rotating torque drive interlock dish of bypass isolating switch, doing all around by the horizontal kinematic link of interlock firmware drive in the connecting rod fixed mount moves horizontally, when bypass isolating switch during at closing position, the postive stop baffle of horizontal kinematic link one end just in time is positioned at the cutter latch-down baffle place, ground that is arranged on the earthed switch power transmission shaft of line side, form the mechanical latching relation, thereby reach the purpose of locking.
In sum, the beneficial effects of the utility model are to realize in same interval, and the mechanical latching relation of the line side earthed switch of bypass isolating switch and line disconnecting switch is thoroughly stopped in the sideband operation accident of charged misconnecting earthed switch.Can extensively use in electric power system, have promotional value, application prospect is preferably arranged.
Description of drawings

Fig. 2 is the assembly structure schematic diagram of the utility model one embodiment.
Embodiment
Below in conjunction with drawings and Examples, the utility model is elaborated:
As shown in Figure 2, be the isolating switch anti-misoperation apparatus that the utility model provides, comprise mechanical linkage dish 3, interlock firmware 4, horizontal kinematic link 7, postive stop baffle 10, the formations such as cutter latch-down baffle 9 and connecting rod fixed mount 5.
As shown in Figure 1, the appropriate location, upper end at the kinematic link 2 of bypass isolating switch 1 is installed with mechanical linkage dish 3, utilizes deciliter rotating torque of isolating switch 1 can drive interlock dish 3 and rotates; As shown in Figure 2,6 installing holes of design on interlock dish 3, to be the better dissimilar isolating switch in job site that adapts to, by selecting different installing holes, regulate the position of horizontal kinematic link 7 other end postive stop baffles 10, the contact-making surface of interlock dish 3 and bypass isolating switch kinematic link 2, can be processed into to increase the prismatic of friction contact-making surface, be bolted again, guarantee interlock dish 3 and isolating switch kinematic link 2 fixing compacts.
As shown in Figure 2, be provided with horizontal kinematic link 7 on interlock dish 3, connect mechanical linkage dish 3 and horizontal kinematic link 7 by interlock firmware 4, interlock firmware 4 is socketed in an end of horizontal kinematic link 7, and insert in the installing hole of mechanical linkage dish 3 lower end of interlock firmware 4.Move with horizontal kinematic link 7 left and right horizontal of the rotation drive of interlock dish 3; Consider the versatility of job site, it is adjustable that horizontal kinematic link 7 is designed to middle screw rod, to adapt to the requirement of different installing spaces.
As shown in Figure 1, on the pedestal channel-section steel 6 of bypass isolating switch 1 and line disconnecting switch 11, connecting rod fixed mount 5 is installed respectively, is used for the support of horizontal kinematic link 7, not increase the mechanical action moment of bypass isolating switch 1; As shown in Figure 2, the Kong Buying on connecting rod fixed mount 5 is the positive circle that is slightly larger than horizontal kinematic link diameter, but oval shape, the requirement that moves forward and backward to satisfy horizontal kinematic link 7.
As shown in Figure 1 and Figure 2, horizontal kinematic link 7 is equipped with postive stop baffle 10 near line disconnecting switch 11 1 sides, when bypass isolating switch 1 during at closing position, this postive stop baffle 10 just in time is positioned at cutter latch-down baffle 9 right sides, ground that are arranged on line side earthed switch power transmission shaft 8, form the mechanical latching relation, thereby reach the purpose of locking.Can by regulating the installation site of postive stop baffle 10, reach the best locking point with ground cutter latch-down baffle 9.In order to leave certain nargin to installation accuracy, will there be certain width the upper end of postive stop baffle 10, can reliably limit the rotation of residence cutter latch-down baffle 9 to guarantee it.
