Abstract
The invention relates to a novel SF6 insulated vacuum load switch cabinet. A fully-sealed air tank is installed in the upper rear part of a cabinet body. Solid-sealed polar poles are installed in the middle of the cabinet body. An isolating knife switch component and a bus connection static contact are installed above each solid-sealed polar pole. A grounding switch is installed at the bottom of the air tank. An outlet casing is installed on the lower front plate of the air tank. A current transformer sleeves the outlet casing. The outer middle of the front plate of the air tank is equipped with an electromagnetic spring mechanism which is used for controlling series asynchronous linkage between the solid-sealed polar poles and the isolating knife switch components. The invention provides an SF6 insulated vacuum load switch cabinet which has the advantages of simple structure, small size, stable insulation performance, long service life and low manufacturing cost.
Description
Technical field
The present invention relates to power system high-tension distribution equipment, a kind of New type of S F6 insulation vacuum loading switch cabinet.
Background technology
Current China 10kV loading switch cabinet design great majority adopt air insulation or SF6 to make arc extinguishing valency matter, insulation distance designs according to air insulation, cabinet molded dimension is relatively larger, electrical body is exposed, erosion by air, dust, easily cause the corrosion of electrical body, reduce product insulating properties, life-span short; The loading switch cabinet of arc extinguishing valency matter is made with SF6, the electric arc produced in interrupting process easily pollutes and damages electric elements in cabinet, impact switch overall performance, and switch internal is full of higher SF6 gas pressure, using by effects of air pressure under high altitude condition, fault rate is higher.
Summary of the invention
The technical problem to be solved is to provide that a kind of simple in construction, volume be little, stable insulation, long service life, and the relatively low SF6 of manufacturing cost insulate vacuum loading switch cabinet.
A kind of New type of S F6 insulation vacuum loading switch cabinet of this practicality includes a cabinet, in cabinet, upper back is provided with a hermetic gas tank being filled with SF6 gas, gas tank is internally provided with: is positioned at the pole at middle part, is positioned at pole and is arranged over isolation knife assembly and bus and connects static contact, be positioned at bottom gas tank to be provided with earthed switch, gas tank bottom header board is provided with outlet casing tube, and current transformer is sleeved on outlet casing tube; Setting electromagnetic spring mechanism at the outer middle part of gas tank header board, its effect controls described pole and serial asynchronous linkage isolation knife assembly.
The inside and outside gas pressure difference of described gas tank is zero.
The internal each phase of described SF6 insulation vacuum load switch gas tank arranges pole.
A kind of New type of S F6 insulation load switch switch cubicle of this practicality adopts vacuum extinction, SF6 gas-insulated, and built-in double-fracture designs, and pole is safe and reliable with the linkage of isolation knife assembly serial asynchronous; This product has all insulation, hermetically sealed, high-pressure electrified conductor does not expose, and small product size is little, compact conformation, cost are low, the feature of life-span length, and product is by the restriction of environmental factors, it is possible to adapts to various rugged environment and uses.

Detailed description of the invention
Referring to Fig. 1, Fig. 2, Fig. 3, present invention is described:
SF6 insulation vacuum load switch includes: cabinet 1, gas tank 2, pole 3, bus connect static contact 4, isolation knife assembly 5, earthed switch 6, outlet casing tube 7, current transformer 8, electromagnetic spring mechanism 9.
As shown in Figure 1, 2, hermetically sealed gas tank 2 is arranged on cabinet 1 upper back, being positioned at installation in the middle part of gas tank 2 is pole 3, pole 3 is connected dependence nut interlocking with main shaft 18, pole 3 isolation knife assembly 5 installed above and bus connect static contact 4, earthed switch 6 is installed bottom gas tank 2, gas tank 2 bottom header board is provided with outlet casing tube 7, current transformer 8 is sleeved on outlet casing tube 7, the outer middle part of gas tank 2 header board is provided with electromagnetic spring mechanism 9, and its effect controls pole 3 and the linkage of isolation knife assembly 5 serial asynchronous.
As it is shown on figure 3, in pole parts 3 built-in parcel vacuum interrupter, interrupting process, arc energy is little, contact burning is few; Upper end arranges safe and reliable POM fairlead, and it acts on, and auxiliary extinction of arc chamber contact vertically-acting, gap be little, contact uniform wear, strengthens the stability that loading switch cabinet divides, closes a floodgate.
As shown in Figure 4, the internal crank connecting link 73 of electromagnetic spring mechanism 9 is connected driving three-phase solid-sealed pole with main shaft 18, and connecting lever connecting rod 74 is connected with isolation knife assembly 5; Electromagnetic spring mechanism 9 manually or electronic stored energy, controls pole 3 and the linkage of isolation knife assembly 5 serial asynchronous, is taken by electromagnetic spring mechanism 9 internal structure design and different makes isolation knife assembly 5 close a floodgate prior to pole 3, after in pole 3 separating brake.
