Description
Technical field
The utility model relates to high voltage power distribution technical field, is specifically related to a kind of high-pressure vacuum switch of cutter with ground.
Background technology
High-pressure vacuum switch after a loss of power its outlet pole can remain high voltage load (voltage), and the life security of these high pressure to people has great threat, if it is very dangerous for not processing participation electric charge and directly touch pole.Therefore, high voltage power distribution staff needs leading-out terminal ground connection when detecting, safeguard or implement scheme of electric power to high-tension circuit, residual, the induced voltage on outlet pole is imported the earth and can carry out overhauling and distribution work.
High-pressure vacuum switch and earthed switch are two kinds of most important high voltage devices in high voltage power distributing cabinet, and the on/off switch operating sequence of these two kinds of switches has strict restriction, and when vacuum switch closes a floodgate, (power transmission) earthed switch can not close a floodgate; When earthed switch closes a floodgate, (ground state) vacuum switch can not close a floodgate (power transmission), both can not close a floodgate simultaneously.In existing electric power system, high-pressure vacuum switch and earthed switch are independently two kinds of electric elements, different positions is arranged in high-tension switch cabinet, independent operation but need reciprocal interlock, there is following shortcoming: because two kinds of switches are independently elements, must and high-tension switch cabinet in other element as effective in instrument transformer and sensor do in size in electric and mechanical aspects, secure fit, the increase of number of elements means that the volume of high-tension switch cabinet increases; In order to ensure both proper operation orders, necessarily giving and installing complicated interlocking device between the two additional, adding extra work to the production of high-tension switch cabinet and debugging; Be limited by space limited in high-tension switch cabinet, restriction is also arrived in the scheme of electric power flexibility of high-tension switch cabinet.
Utility model content
For above problem, the utility model provides a kind of high-pressure vacuum switch of cutter with ground.
The utility model is achieved through the following technical solutions:
A high-pressure vacuum switch for cutter with ground, comprises high-pressure vacuum switch pole and operating mechanism case; Also comprise earthing, described earthing comprises earthing fixed contact, earthing moving contact and earthing operating axis; Earthing fixed contact is arranged under the pole of high-pressure vacuum switch pole on terminals, and earthing fixed contact is connected with terminals conductors under pole; Earthing operating axis is located on operating mechanism case, is in transmission connection with operating mechanism case; Earthing moving contact is arranged on earthing operating axis, and earthing moving contact is connected with the Special grounding point conductor on operating mechanism case.
Further, on the pole of described high-pressure vacuum switch pole, terminals can be arranged in the position vertically upward of high-pressure vacuum switch pole, also can be arranged in the top position, side of high-pressure vacuum switch pole.
Further, the layout of described high-pressure vacuum switch pole on operating mechanism case can be laterally, also can be longitudinal.
Further, described earthing fixed contact is arranged under the pole of high-pressure vacuum switch pole on terminals, and earthing operating axis to be positioned under pole below terminals.
After adopting technique scheme, the beneficial effects of the utility model are:
1, the function that vacuum switch and earthed switch is combined as a whole unites two into one, and reduces the space occupied in high-tension switch cabinet, and then reduces the volume and weight of high-tension switch cabinet, make the structure in high-tension switch cabinet compacter;
2, without the need to refilling independently earthed switch in addition, the enforcement of scheme of electric power is convenient, and the interlocking device between two kinds of switches is placed in same operating mechanism case, significantly reduces the production of relevant device, installation and adjustment works, efficient quick flexible and convenient to use;
3, use same operating mechanism case to carry out action interlocking association to two kinds of switches, security performance is better.

Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
embodiment:a high-pressure vacuum switch for cutter with ground, as shown in the figure, comprises high-pressure vacuum switch pole 1 and operating mechanism case 2; Also comprise earthing, described earthing comprises earthing fixed contact 31, earthing moving contact 32 and earthing operating axis 33.Earthing fixed contact 31 to be arranged under the pole of high-pressure vacuum switch pole 1 on terminals 11, is connected with terminals 11 conductor under the pole of high-pressure vacuum switch pole 1.Earthing operating axis 33 is located on operating mechanism case 2, being in transmission connection with operating mechanism case 2, (operating mechanism case 2 can drive earthing operating axis 33 to rotate a certain angle, this is the common function action of appliance switch operating mechanism case, no longer repeats the action principle of operating mechanism case).Earthing moving contact 32 is arranged on earthing operating axis 33, and earthing moving contact 32 is connected with the Special grounding point conductor on operating mechanism case 2.On the pole of high-pressure vacuum switch pole 1, terminals 12 can be arranged in the position vertically upward (as shown in Figure 1) of high-pressure vacuum switch pole 1, also can be arranged in the top position, side (as shown in Figure 3) of high-pressure vacuum switch pole 1.The layout of high-pressure vacuum switch pole 1 on operating mechanism case 2 can be laterally (as shown in Figure 4), also can be longitudinal (as shown in Figure 5).Earthing fixed contact 31 is arranged under the pole of high-pressure vacuum switch pole 1 on terminals 11, and earthing operating axis 33 to be positioned under pole below terminals 11.
Before electrical equipment in high-tension switch cabinet is overhauled, rely on operating mechanism case 2 that moving contact 14 in vacuum interrupter 13 is separated with fixed contact 15, thus disconnect high-tension electricity; Then, operating mechanism case 2 orders about earthing operating axis 33 and rotates a certain angle, drive earthing moving contact 32 upwards upset and earthing fixed contact 31 phase butt (as shown in Figure 2), thus be connected with the earth connection of distribution system with the Special grounding point on operating mechanism case 2 through earthing by terminals under pole 11, and then ensure the personal safety of maintainer.
