Abstract
本实用新型公开了电力输变电系统中的一种户内高压接地开关的辅助开关安装结构。是在接地开关主体结构和传动结构上，把辅助开关(10)直接安装在接地开关基架(12)上，并在接地开关转轴(8)上固定安装一凸轮(11)。避免电气误操作的出现和控制，从而保证电网的安全、稳定、经济运行，对变电站内倒闸、检修等工作提供了可靠的技术保障。
The utility model discloses an auxiliary switch installation structure of an indoor high-voltage grounding switch in a power transmission and transformation system. On the grounding switch main structure and transmission structure, the auxiliary switch (10) is directly installed on the grounding switch base frame (12), and a cam (11) is fixedly installed on the grounding switch rotating shaft (8). Avoid the occurrence and control of electrical misoperation, thereby ensuring the safe, stable and economical operation of the power grid, and providing reliable technical support for switching, maintenance and other work in substations.
Description
Technical field
The utility model relates to the indoor hv earthing switch in a kind of electric power power transmission and transformation system, and the interior earthed switch of special and switchgear is relevant.
Background technology
In electric power power transmission and transformation system, particularly 6kV, 10kV, 35kV medium voltage network switchgear, under situation such as switchgear maintenance, need ground connection.Earthed switch is as the earthing device of necessity, and the normal operation and the maintenance of switching devices play a part very important.The auxiliary switch mounting configuration of existing earthed switch is as shown in Figure 1; Earthed switch operating axis 2 is fixed on the cabinet 1; Be fixed with connecting lever 5 in the earthed switch rotating shaft 2, in earthed switch rotating shaft 8, be fixed with connecting lever 9 down, earthed switch operating axis 2 and last connecting lever 5, connecting rod 6 and the following connecting lever 9 common running parts that constitute earthed switches; Auxiliary switch 10 is installed on the cabinet 1, on earthed switch operating axis 2, is fixed with a fanning strip 3.
Receive in earthed switch rotating shaft 2 under the situation of input power,, make down connecting lever 9 rotations, thereby the branch that closes that is grounded switch is operated through 6 motions of last connecting lever 5 drivening rods; Auxiliary switch 10 is at the active force that receives fanning strip 3, realize auxiliary switch 10 auxiliary contact close branch, the sub-signal that closes of earthed switch is provided for switchgear.But; The fixing spring pivot 4 of going up connecting lever 5; The phenomenon that under long-time operation and stressed situation, can occur dropping, thus can cause earthed switch the empty empty phenomenon of closing of dividing to occur, and this moment, auxiliary switch 10 closed sub-signal output to mistake; Under the situation circuit breaker operated like this and will cause electric misoperation; Electrical network, switchgear and power consumption equipment are damaged, cause huge threat and destruction for device security, personal safety and power grid security, even possibly cause the collapse of whole network.
The utility model content
The purpose of the utility model is to adapt to prevent that switchgear band earthed switch from carrying out the needs that electric misoperation appears in breaker closing, designs a kind of auxiliary switch mounting configuration of indoor hv earthing switch.
The technical scheme that the utility model adopts is: a kind of auxiliary switch mounting configuration of indoor hv earthing switch; It is characterized in that; On earthed switch agent structure and drive mechanism, be directly installed on auxiliary switch on the earthed switch pedestal, and in the earthed switch rotating shaft, fixedly mount a cam.
When earthed switch closed the branch operation, the earthed switch rotating shaft drove the cam rotation, and the cam of rotation is pushed down the roller of auxiliary switch, thereby realizes the closure and the segmentation of auxiliary switch contact, guaranteed that correct earthed switch closes sub-signal output.
The auxiliary switch mounting configuration of the indoor hv earthing switch that the utility model provides; Under the situation of agent structure that does not change existing earthed switch and earthed switch drive mechanism; Avoid the appearance and the control of electric misoperation; Thereby guarantee safe, stable, the economical operation of electrical network, and also reliable guidance is provided work such as back brake, maintenance in the transformer station.
Description of drawings
Fig. 1 is the structural representation of existing indoor hv earthing switch auxiliary switch mounting configuration and drive mechanism;
Fig. 2 is the structural representation of the auxiliary switch mounting configuration of the utility model indoor hv earthing switch.
Embodiment
Below in conjunction with accompanying drawing the utility model is described further.
Among the figure: 1, cabinet 2, earthed switch operating axis 3, fanning strip 4, spring pivot 5, last connecting lever 6, connecting rod 7, cone pin 8, earthed switch rotating shaft 9, following connecting lever 10, auxiliary switch 11, cam 12, earthed switch pedestal
Shown in accompanying drawing 2; The auxiliary switch mounting configuration of the utility model indoor high-voltage ground connection; Be on earthed switch agent structure and drive mechanism, be directly installed on auxiliary switch 10 on the earthed switch pedestal 12, and in earthed switch rotating shaft 8, fixedly mount a cam 11.
Receive under the external force effect in earthed switch rotating shaft 8 and to rotate; Close normally exceptionally being grounded switch, also drive cam 11 rotations, under the driving of cam 11; Force the auxiliary switch 10 that is fixed on the earthed switch pedestal 12 to move, thereby guaranteed to close normally sub-signal output.
The auxiliary switch mounting configuration of this indoor high-voltage ground connection has been avoided empty the branch under the empty situation of closing occurring at earthed switch fully, and the mistake of auxiliary switch 10 outputs is closed sub-signal, as long as earthed switch is failure to actuate (closing branch), does not just have and closes sub-signal output accordingly.Thereby guarantee safe, stable, the economical operation of electrical network, avoid the generation of this type of electric fault-operation accident, and also reliable guidance is provided work such as back brake, maintenance in the transformer station.
