Abstract
A secure high voltage grounding switch. The utility model comprises a three-phase static contact and a three-phase moving contact matched with the three-phase static contact which are arranged on the seat frame, an inner rotating axle and an outer rotating axle embedded at the identical axle center are arranged on the seat frame, one phase of the three-phase moving contact is fixedly connected with the inner rotating axle, the other two phases are fixedly connected with the outer rotating axle, driven bevel gears arranged with partial engaging teeth are respectively arranged at the identical axle ends of the two rotating axle, and a dual driving bevel gear is arranged on the seat frame, which is meshed with the two driven bevel gears. Through the meshing of the dual driving bevel gear and the two driven bevel gears with partial teeth, the utility model drives the two inner and outer rotating axle to rotate respectively, the accomplish the earlier single phase grounding and the sequent grounding of the other two phases of the three-phase grounding switch, therefore to realize the accomplishment of the single phase grounding during the process of the closing of the high voltage grounding switch, and avoid the human and equipment damage accident caused by electrified closing of the three-phase grounding switch.
Description
Technical field
The utility model relates to electric switch, is specifically related to a kind of safety high-pressure earthed switch.
Background technology
During to high pressure power consumption equipment interruption maintenance, must carry out the processing of reliable ground connection, to guarantee the safety of maintenance personal and equipment.The earthed switch that is used for high-tension switch cabinet has at present generally adopted contact three-phase synchro switch, the problem that this three synchronised high voltage ground switch exists is, when equipment during at charging operation, if close earthed switch, can cause the serious person and device security accident, although after in the power consumption equipment maintenance safety operational procedure equipment being had a power failure the electrical verification requirement is arranged, but by charged for some reason, or personal injury and device damage accident that charged joint three-phase earthed switch causes, still generation often owing to maintainer's operate miss.
Summary of the invention
The purpose of this utility model is at the problems referred to above, and a kind of safety high-pressure earthed switch that can effectively avoid missing charged joint three-phase earthed switch and cause the person and equipment damage accident is provided.
The technical scheme that realizes above-mentioned purpose is, a kind of safety high-pressure earthed switch, it includes the three-phase fixed contact that is fixedly set on the mounting and the three-phase moving contact of phase configuration with it, its mounting is provided with an interior rotation axis and an outer rotation axis of the nested assembling of concentric, in the described three-phase moving contact one fixedlyed connected with interior rotation axis, two-phase is fixedlyed connected with outer rotation axis in addition, same axle head at two rotation axiss is separately installed with the driven bevel gear that local engaging tooth is set, and is meshed with two driven bevel gears to be provided with initiatively conical gear of a duplex in mounting.
The technical solution of the utility model also comprises: matching with rotation axis places mounting to be provided with bearing pedestal.
The utility model is arranged to the engagement of local toothed driven bevel gear by duplex active conical gear and two, driving inside and outside two rotation axiss rotates respectively, finish the single-phase earthing in advance of three-phase earthed switch and follow-up other two phase ground, thereby the realization high voltage ground switch is finished the electrical verification operation of single-phase earthing in the process of closing a floodgate, avoid the personnel and the equipment damage accident that take place because of the charged joint three-phase earthed switch of mistake.
Description of drawings
Accompanying drawing is a safety high voltage ground switch structural representation.
Embodiment
In conjunction with the accompanying drawings embodiment of the present utility model is described.
Provide as accompanying drawing, the safety high voltage ground switch has the mounting 1 that is arranged in the switch cubicle, on mounting 1, be set with three-phase fixed contact 2 by insulator, and nested assembling one an interior rotation axis 4 and the outer rotation axis 5 of concentric, with the three-phase moving contact 3 of three-phase fixed contact 2 phase configuration one in insulating bar is fixedly set on the rotation axis 4, the two-phase moving contact is outside insulating bar is fixedly set on the rotation axis 5 in addition, same axle head at two rotation axiss is installed with the driven bevel gear 6 and 7 that local engaging tooth is set respectively, the duplex active conical gear 8 that is meshed with driven bevel gear 6 and 7 and is equipped with center band handle hole on mounting 1.
When the utility model is specifically implemented, three-phase moving contact links to each other with ground loop, when carrying out the ground connection operation, utilize action bars to rotate driving gear 8,, make the continuous of three-phase fixed contact that a phase and phase of three-phase moving contact answers by the rotation of rotation axis 4 at first driving gear 8 and cooperating of driven bevel gear 7, finish the electrical verification operation of single-phase earthing, this moment is if equipment is charged, system's signal that gives the alarm immediately, thus avoid proceeding of misconnection ground operation.After electrical verification is errorless, be rotated further action bars, by the engagement of gear 8, the other two-phase of three-phase moving contact is connected with the other two-phase of corresponding three-phase fixed contact with gear 6, finish whole operations of equipment three-phase shortcircuit ground connection.
As accompanying drawing, the utility model is provided with bearing pedestal 9 and cooperates with rotation axis 4 and rotation axis 5 on mounting 1, to improve the rotation flexibility of two rotation axiss.
Claims (2)
1. safety high-pressure earthed switch, include the three-phase fixed contact (2) that is fixedly set on the mounting (1) and the three-phase moving contact of phase configuration (3) with it, it is characterized in that: mounting (1) is provided with an interior rotation axis (4) and an outer rotation axis (5) of the nested assembling of concentric, in the described three-phase moving contact (3) one fixedlyed connected with interior rotation axis (4), two-phase is fixedlyed connected with outer rotation axis (5) in addition, same axle head at two rotation axiss is separately installed with driven bevel gear (6) and (7) that local engaging tooth is set, and is meshed with two driven bevel gears (6) and (7) to be provided with initiatively conical gear (8) of a duplex in mounting (1).
2. safety high-pressure earthed switch according to claim 1 is characterized in that: matching with rotation axis (6) and (7) places mounting (1) to be provided with bearing pedestal (9).
