Abstract
The utility model discloses an insulation sleeve barrel used for 24 kV high-pressure vacuum fixed sealing electrode poles. The whole body of the insulation sleeve barrel is in a step-shaped round barrel, the middle of the step-shaped round barrel is thin, both ends of the step-shaped round barrel are thick, one end of the round barrel is provided with an outer layer sleeve barrel (1), a round hollow sandwich layer (3) is arranged between the outer layer round barrel (1) and an insulation sleeve barrel (2), and the outer layer sleeve barrel (1) and the insulation sleeve barrel (2) are in a thick wall (4) structure at the inner connecting part. The wire outlet arm port of a fixed sealing electrode pole of the circuit breaker is completely covered by the insulation sleeve barrel, the insulation sleeve barrel is closely matched with the wire outlet arm port of the fixed sealing electrode pole for reaching the effects of supporting and insulation enhancement, the outer layer sleeve barrel and the hollow structure enlarge the creep age distance between a conductive part of the vacuum circuit breaker and the outside, the thick wall structure enhances the insulation on a separation plate in a switch cabinet by a connecting part of a copper touch arm and an upper conductive block in the insulation barrel, the structure effectively solves the problems of insulation on a case of a set of switch cabinets by a conducting touch arm of the circuit breakers and the insulation between the circuit breakers, and reduces the insulation distance, so the miniaturization of the circuit breaker is possible, and the operation of electric equipment is safe and reliable.
Description
Technical field
The utility model relates to the indoor ac high-voltage pole vacuum circuit-breaker in a kind of electrical power distribution system, and is special relevant with the insulation system of the indoor ac high-voltage pole of 24kV vacuum circuit-breaker.
Background technology
Development along with China's power technology and power product, the positive penetration and promotion of 24Kv electric pressure, from economic angle, 10Kv switchyard upgrading is the very material benefit of 24Kv switchyard, extremely urgent, the developing market of 24Kv electric pressure product miniaturization has a extensive future.At present, the development of miniaturization circuit breaker is very fast both at home and abroad, but the development of miniaturization circuit breaker, the problem that must bring insulating capacity to reduce, the air-insulated pole vacuum circuit-breaker of the little electric current 210mm of 24Kv electric pressure spaced apart particularly, the quiet end of galvanic circle contact Insulation Problems alternate and over the ground is difficult to solve especially.Conventional solution is to install insulating barrier additional, the perhaps coated heat-shrinkable T bush of copper conduction contact arm, or do vulcanizing treatment.These way cost height, technology is loaded down with trivial details, and the Insulation Problems between the relative voltage switchgear housing in circuit breaker limit can not solve the alternate and circuit breaker of circuit breaker effectively and cooperate with switch cubicle the time.This problem becomes the obstacle of 24Kv product miniaturization development.
Summary of the invention
The utility model is little at present 24Kv electric pressure miniaturization air insulation pole vacuum circuit-breaker size, phase spacing is little, and circuit breaker when cooperating with switch cubicle the little and a kind of suitable pole circuit breaker miniaturization designed and developed of the insulation distance between circuit breaker and voltage switchgear housing to insulation and the creepage 24Kv high pressure vacuum pole circuit breaker insulating sleeve that requires than distance.
The technical solution of the utility model is: a kind of 24Kv high pressure vacuum pole circuit breaker insulating sleeve, it is characterized in that, insulating sleeve integral body is middle thin, the thick stairstepping cylinder in two ends, one end is provided with outer layer sleeve, between outer cylinder and the insulating sleeve is circular hollow interlayer, and outer layer sleeve and insulating sleeve are thick-walled structure in interior junction.
The 24Kv high pressure vacuum pole circuit breaker insulating sleeve that the utility model provides, after fixedly mounting with circuit breaker, the quiet end conductive component of contact of breaker covers fully, forms with the outside and isolates, and has satisfied the miniaturization of pole circuit breaker to insulation and creepage requirement than distance.Outer layer sleeve, hollow interlayer and heavy wall have improved the intensity of sleeve, make the cylindrical shell shrinkage stress even, have avoided the ovalizing deflection of the products solidifying process that causes because of shrinkage stress is irregular, have improved the rate of finished products of product greatly.
Description of drawings
Fig. 1 is the main TV structure schematic diagram of the utility model 24Kv high pressure vacuum pole circuit breaker with an embodiment of insulating sleeve;
Fig. 2 is a plan structure schematic diagram embodiment illustrated in fig. 1.
Embodiment
The utility model is described in further detail below in conjunction with accompanying drawing.
Among the figure 1, outer layer sleeve 2, insulating sleeve 3, hollow interlayer 4, heavy wall
As shown in the figure, the utility model 24Kv high pressure vacuum pole circuit breaker is middle thin, the thick stairstepping cylinder in two ends with insulating sleeve integral body, one end is provided with outer layer sleeve (1), between outer cylinder (1) and the insulating sleeve (2) is circular hollow interlayer (3), and outer layer sleeve (1) and insulating sleeve (2) are heavy wall (4) structure in interior junction.
During use, there is outer layer sleeve one end inner layer sleeve to be sleeved on the leading-out terminal of pole, contact arm is contained in the insulating sleeve, by screw on the outlet arm, rely on the back-up ring of adorning on the contact arm, block insulating sleeve and come off, outer layer sleeve plays insulating effect, the hollow interlayer that outer layer sleeve and sleeve form has strengthened the creepage distance of circuit breaker to the outside, and heavy wall has improved the intensity of sleeve and strengthened the insulation of pole to the cabinet median septum.This structure has reduced insulation distance effectively, makes the circuit breaker miniaturization become possibility, and electric equipment operation is more safe and reliable.
