Abstract
The invention discloses a medium-pressure mid-set movable solid-sealed type vacuum switch, which mainly comprises a solid-sealed pole, a vacuum arc extinguishing chamber, a current limiting fuse and an operating mechanism. Both the vacuum arc extinguishing chamber and the current limiting fuse are arranged in the solid-sealed pole and connected in series to form a series loop. Because the vacuum arc extinguishing chamber and the current limiting fuse are combined in the T-shaped solid-sealed pole and the functions of the both are combined together, the vacuum switch has the functions of realizing a vacuum circuit breaker, a vacuum load switch, a combined electric appliance of the vacuum load switch and a fuse, a vacuum contactor, an F-C loop and the like and is convenient for a user to select the type.
Description
Technical field
The present invention relates to the used switchgear of a kind of electric power system, particularly relate to the mid-withdraw-type of a kind of middle pressure and seal vacuum switch admittedly.
Background technology
Middle pressure withdraw-type vacuum circuit-breaker is to belong to the widely used main key switchgear of distribution system, can supply industrial and mining enterprises and the transformer station usefulness as the control and the protection of electrical equipment facility.In the terminal temperature difference of electric power system, also be used widely, in user's utilization and operation, can run into following two difficult problems;
1 user's secondary control power supply is often not too reliable, makes handcart type breaker not protect distribution transformer by action message.
The intrinsic operate time of 2 vacuum circuit-breakers than (≤60ms) vacuum load switch-fuse combined electric apparatus operate time long (≤20ms), the latter can more effective protection distribution transformer.
The middle middle vacuum load switch of pressing, though solved on-load switch can not with the supporting historical blank that is used in intermediate switchgear cabinet of main flow circuit breaker (handcart type breaker), (must with the supporting use of main flow handcart type breaker) be restricted but because its structure mounting means, the high-capacity vacuum arc control device can not be installed, limit the middle vacuum load switch and replaced main flow circuit breaker (handcart circuit breaker) to be widely used in the distribution system.
Summary of the invention
The object of the present invention is to provide to press solidly envelope withdraw-type vacuum switch in a kind of, it can realize functions such as vacuum circuit-breaker, vacuum load switch, vacuum switch-fuse combined electric apparatus, vacuum contactor, F-C loop by user's request.
For achieving the above object, technical solution of the present invention is:
The present invention presses solidly envelope withdraw-type vacuum switch in a kind of, and it mainly is made up of pole, vacuum interrupter, high-voltage and current-limitation fuse, operating mechanism; Vacuum interrupter is installed in (in the vertical hollow cylinder) in the vertical pole, and the high-voltage and current-limitation fuse level is installed in the insulating cylinder (in the horizontal hollow cylinder), and vacuum interrupter and current limiting fuse are connected in series.
Described pole is to intersect cylinder by vertical-horizontal to constitute, profile is "T"-shaped shape, high-voltage and current-limitation fuse is nested with in the level insulation tube (in the horizontal hollow cylinder), the solid big envelope of vacuum interrupter is put in vertical pole body (in the vertical hollow cylinder), operating mechanism and its being connected to form one of compactness structure.
After adopting such scheme, since the present invention be in press solidly sealing type vacuum circuit breaker with in press solidly on the basis of sealed type vacuum switch-fuse combination, organically vacuum interrupter and high-voltage and current-limitation fuse are combined in the T-shape pole by the solid encapsulation technique of epoxy resin APG, both functions are combined, make the present invention possess functions such as the vacuum circuit-breaker of realization, vacuum load switch, vacuum load switch one fuse combined electric apparatus, vacuum contactor, F-C loop, made things convenient for user's type selecting.
Among the present invention in press solidly sealing type vacuum circuit breaker and increased fuse element, be combined into vacuum circuit-breaker-fuse combined electric apparatus, realized vacuum circuit-breaker-fuse combined electric apparatus protection power consumption equipment.
The present invention is further illustrated below in conjunction with the drawings and specific embodiments.
Description of drawings
Fig. 1 is a cutaway view of the present invention;
Fig. 2 is the circuit theory diagrams of first embodiment of the invention;
Fig. 3 is the circuit theory diagrams of second embodiment of the invention.
Embodiment
As shown in Figure 1, the present invention is a kind of middle mid-withdraw-type vacuum switch that seals admittedly of pressing, and it mainly is made up of pole 1, vacuum interrupter 2, high-voltage and current-limitation fuse 3, operating mechanism 4 parts.
Described pole 1 is to be made of with vertical hollow cylinder 12 the horizontal hollow cylinder 11 that intersects vertically, the T-shaped shape of profile, high-voltage and current-limitation fuse 3 is nested with in the level insulation tube (in the horizontal hollow cylinder 11), vacuum interrupter 2 solid big envelopes are put in vertical pole body (in the vertical hollow cylinder 12), high-voltage and current-limitation fuse 3 is connected with vacuum interrupter 2, forms series loop.
The present invention is enclosed in parts such as vacuum interrupter 2 and binding post in the epoxy resin admittedly, forms T-shape pole 1.Pole 1 structure has been avoided the influence to vacuum interrupter 2 external insulations of dust, humidity, geographical position, and reduced the adjustment link of vacuum switch, effectively guarantee the uniformity of parts, having improved reliability of products. current limiting fuse 3 is installed in T-shape pole 1 top, its structural design takes into full account the Electric Field Distribution of vacuum switch in intermediate switchgear cabinet, greatly reduced the adverse effect of inductive element, improved the dielectric strength of cabinet complete sets of products the withstand voltage experiment of cabinet.
Because the present invention is combined in vacuum interrupter 2 and high-voltage and current-limitation fuse 3 in the T-shape pole 1 by the solid encapsulation technique of epoxy resin APG, both functions are combined, shown in Figure 2 is exactly one embodiment of the present of invention, vacuum load switch--fuse combined electric apparatus, it comprises vacuum interrupter 2 ' and high-voltage and current-limitation fuse 3; Shown in Figure 3 is exactly an alternative embodiment of the invention, vacuum circuit-breaker--fuse combined electric apparatus, it comprises high-voltage and current-limitation fuse 3 and vacuum interrupter 2 ".
Operation principle of the present invention:
Since the present invention be in press solidly sealing type vacuum circuit breaker with in press solidly on the basis of sealed type vacuum switch-fuse combination, organically vacuum interrupter 2 and current limiting fuse 3 are combined in the T-shape pole 1 by the solid encapsulation technique of epoxy resin APG, both functions are combined, make the present invention possess functions such as the vacuum circuit-breaker of realization, vacuum load switch, vacuum load switch-fuse combined electric apparatus, vacuum contactor, F-C loop, made things convenient for user's type selecting.
