Description
Affiliated technical field
The present invention relates to the switchgear assembly in a kind of 3.6kV of being applicable to～40.5kV three-phase ac power system; especially a kind of high-tension switch cabinet that comprises one group of high-voltage rotating type integrated switch at least, in electrical power trans mission/distribution system as be subjected to electricity, send electricity, the usefulness of control and protection.
Background technology
At present; known high-tension switch cabinet is made up of parts such as high-voltage switch gear and control, measurement, protection, adjusting device and auxiliary, shell and supporter and electric and mechanical connection thereof, and wherein high-voltage switch gear has isolating switch, circuit breaker, contactor, fuse, on-load switch and earthed switch.These switches are independent separately usually, or constitute combined electrical apparatus by wherein two or more, for example with the switch-fuse combination of earthed switch.Because these switches are independence or carried out simply combination separately, make that the high-tension switch cabinet volume of being made up of it is big, interlocking device is complicated, profile disunity between each switch cubicle, assembling difficulty, the raw material that consume are more.
Summary of the invention
Problems such as the volume that present high-tension switch cabinet exists is big, interlocking device is complicated in order to solve, profile disunity between each switch cubicle, assembling difficulty, the raw material that consume are more the invention provides a kind of high pressure switchgear assembly.This equipment disposition is flexible, simple in structure, profile is unified, volume is little, cost is low, can satisfy the requirement of various main circuits.
The technical solution adopted for the present invention to solve the technical problems is: according to the requirement of a main circuit; substitute common isolating switch, circuit breaker, contactor, fuse, on-load switch, earthed switch or combined electrical apparatus with one group of high-voltage rotating type integrated switch; high-voltage rotating type integrated switch is assemblied in the shell with support effect; be equipped with control corresponding, measurement, protection, adjusting device and auxiliary again; and these parts are carried out electric and mechanical connection, form high-tension switch cabinet with a function that main circuit requires.
Below in conjunction with embodiment concrete formation of the present invention is described.
Fig. 1 is the profile of one embodiment of this invention;
Fig. 2 is the profile of critical component high-voltage rotating type integrated switch of the present invention.
As shown in Figure 1, the left side of figure is the front of this embodiment, and the right side is the back of this embodiment.The main part of this scheme is shell (1) and the installation high-voltage rotating type integrated switch (3) wherein with support effect.High-voltage rotating type integrated switch (3) comprises the operation interlocking mechanism that is positioned at the front and is positioned at the Switch main body of back; Operation interlocking mechanism is covered by mechanism's box (13), and the upper end of Switch main body is connected with main bus bar (2), and the lower end is connected with branch bar (4); In shell (1), the upper space of Switch main body is a bus-bar room, and the lower space of Switch main body is the cable vault.What be connected with branch bar (4) is external cable (6), and the trunk of external cable (6) passes transducer (7), and current transformer (5) passes in each phase branch of external cable (6).Transducer (7) is fixed on the external cable (6), and current transformer (5) then is fixed on the shell (1).External cable (6) passes cable seal circle (9), and is fixing by cable bearer (8) and cable clip (10).In the front of cable bearer (8) and cable clip (10) is earth bus (11), is Xiamen (12) below mechanism's box (13), is instrument box (14) above mechanism's box (13), and adjacent with instrument box (14) is little bus (15).
High-voltage rotating type integrated switch is a critical component of the present invention.As shown in Figure 2, high-voltage rotating type integrated switch is that the benchmark from-inner-to-outer is insulation rotating member (2) and insulation support member (1) with axis of rotation X-X, insulation support member (1) is a hollow, insulation rotating member (2) is positioned at wherein, and insulation rotating member (2) and insulation support member (1) constitute the body of this integrated switch; The left end of axis of rotation X-X is operation interlocking mechanism (3), is fixed on the insulation support member (1).Internal fixation at insulation rotating member (2) has the blow-out element, and outer surface is fixed with moving contact, is connected by conductor between blow-out element and the moving contact; The inside surface distributed of insulation support member (1) fixed contact, and the outer surface outside termination that distributing is connected by conductor between fixed contact and the outside termination.When operation interlocking mechanism (3) drives insulation rotating member (2) around axis of rotation X-X rotation, realize moving contact and fixed contact deciliter, formation multi-functional position isolating switch; Operation interlocking mechanism (3) also can carry out and accept the branch closing operation of blow-out element, and makes and cooperatively interact between these minutes closing operation to realize the desired function of main circuit one time.
The integrated switch of this kind structure is based on insulation support member (1), insulation rotating member (2) and operation interlocking mechanism (3), can be neatly the function of various switch elements be integrated according to the requirement of a main circuit, different schemes has identical essential structure and profile, operation interlocking mechanism has concentrated the various operations to switch, and its intrinsic structure can realize extremely reliable natural interlocking.Especially the integrated switch of this kind structure is reasonable to space utilization, and more common high-voltage switch gear of its volume or combined electrical apparatus are reduced greatly, and cost also reduces greatly simultaneously.With this integrated switch is that the high-tension switch cabinet of critical component equally also has above characteristics and advantage.
The invention has the beneficial effects as follows: flexible configuration, simple in structure, profile is unified, volume is little, cost is low.
