Abstract
The utility model discloses an indoor high pressure vacuum breaker which comprises an operating mechanism, three vacuum arc-extinguish chambers and a mechanism box provided with steel plates in welded mode, six insulators are fixedly connected with the mechanism box, and the three vacuum arc-extinguish chambers are respectively and fixedly connected with the insulators through three upper leading-out ends and three lower leading-out ends. Flexible connections arranged on the lower leading-out ends are fixedly connected with conducting clamps of moving conducting rods at the bottom of the vacuum arc-extinguish chambers, and a tube-shaped insulation cylinder is lengthways sleeved outside each vacuum arc-extinguish chamber. The indoor high pressure vacuum breaker has the advantages of being simple in structure, convenient to install, low in cost, long in service life, strong in opening and closing performance and the like. The indoor high pressure vacuum breaker is greatly resistant to creepage because the vacuum arc-extinguish chambers are vertically arranged in the tube-shaped insulation cylinders. In addition, the indoor high pressure vacuum breaker can not only prevent the vacuum arc-extinguish chambers from being damaged by external factors, but also ensure that high impedance is presented for voltage effects even under damp and hot and serious dirty environment.
Description
Technical field
The utility model belongs to breaker technical field, relates to a kind of indoor high-voltage vacuum circuit breaker specifically.
Background technology
Indoor high-voltage vacuum circuit breaker is the indoor switchgear that is used for electric power system; Protection and control unit as grid equipment, industrial and mining enterprises' power-equipment; Since the special superiority that vacuum circuit-breaker has, the place that is particularly useful for the frequent operation of requirement rated operational current or repeatedly cut-offs short circuit current.But indoor high-voltage vacuum circuit breaker of the prior art have volume big, shortcomings such as complicated, that cost is high, fragile are installed, so how can provide that a kind of volume is little, simple installation, indoor high-voltage vacuum circuit breaker with low cost, long service life become the urgent demand of people.
The utility model content
The utility model is in order to overcome the deficiency that prior art exists, and provides that a kind of volume is little, the indoor high-voltage vacuum circuit breaker of simple installation, with low cost, long service life.
The utility model is realized through following technical scheme: a kind of indoor high-voltage vacuum circuit breaker; Comprise operating mechanism, three vacuum interrupters and a mechanism case that is welded by steel plate; On mechanism case, be fixedly connected with six insulators; Three vacuum interrupters go up leading-out terminals through three respectively and three lower wire ends are fixedly connected on the insulator, and lower wire end is provided with and is flexible coupling, be flexible coupling with vacuum interrupter bottom moving conductive rod on conductive clip affixed; In mechanism case, be provided with switch spindle; Switch spindle is connected with moving conductive rod through three insulated pull bars, and insulated tension pole is provided with touch spring, at the outdoor equal longitudinal sleeve of each vacuum extinction a tubulose insulating cylinder is housed.
Said tubulose insulating cylinder is built by epoxy resin and is formed.
Said operating mechanism is a spring operating mechanism, has manual energy storage and electric energy-stored, and breaker closing institute energy requirement is provided by the energy storage of combined floodgate spring, and energy storage both can be accomplished by the external power source drive motors, also can use the energy storage handle manually to accomplish.
Said switch spindle passes to power the moving guide rod that makes switch combined floodgate, separating brake through three insulated pull bars.
The beneficial effect of the utility model is: the indoor high-voltage vacuum circuit breaker volume of the utility model is little; The diffuse arc electric current that produces when cut-offfing distributes consistent on contact; The partial melting phenomenon can not appear; And have advantages such as simple in structure, simple installation, with low cost, long service life, connecting-disconnecting function be strong,, be particularly useful for cut-offfing the place of important load and frequent operation adaptable across the control or the protection switch of distribution systems such as power plant, transformer station.The vacuum interrupter of the utility model circuit breaker vertically is installed in the tubulose insulating cylinder, and insulating cylinder adopts APG technology to build by epoxy resin and forms, so very anti-creepage.This structural design reduces dust greatly to be gathered on the vacuum interrupter surface, can prevent that not only vacuum interrupter from receiving the damage of external factor, even and can guarantee under the environment of damp and hot and pollution severity, also can demonstrate high-impedance state to voltage effects.
Description of drawings
Fig. 1 is the structural representation of a kind of indoor high-voltage vacuum circuit breaker of the utility model;
Among the figure: 1-vacuum interrupter, the last leading-out terminal of 2-, 3-lower wire end, 4-insulator, 5-mechanism case, 6-switch spindle, 7-insulated tension pole, 8-touch spring, 9-conductive clip, 10-are flexible coupling.
Embodiment
Below in conjunction with accompanying drawing the utility model is described in detail.
As shown in Figure 1; A kind of indoor high-voltage vacuum circuit breaker; Comprise operating mechanism, three vacuum interrupters 1 and a mechanism case 5 that is welded by steel plate, 4, three vacuum interrupters 1 of six insulators are gone up leading-out terminals 2 through three respectively and three lower wire ends 3 are fixedly connected on the insulator 4 being fixedly connected with on the mechanism case 5; Lower wire end 3 is provided with and is flexible coupling 10; Be flexible coupling 10 with vacuum interrupter 1 bottom moving conductive rod on conductive clip 9 affixed, in mechanism case 5, be provided with switch spindle 6, switch spindle 6 is connected with moving conductive rod through three insulated pull bars 7; Insulated tension pole 7 is provided with touch spring 8, and all longitudinal sleeve is equipped with a tubulose insulating cylinder outside each vacuum interrupter 1.The tubulose insulating cylinder is built by epoxy resin and is formed, and said operating mechanism is a spring operating mechanism.
The current path of the utility model circuit breaker major loop when closing position is: go up leading-out terminal 2 through being fixed on upper bracket on the vacuum interrupter 1 to the inside fixed contact of vacuum interrupter 1; Through the conductive clip 9 of moving contact and connection thereof, be flexible coupling 10, to lower carriage to lower wire end 3.
Should be noted that at last; Above content is only in order to explain the technical scheme of the utility model; But not to the restriction of the utility model protection range; The simple modification that those of ordinary skill in the art carries out the technical scheme of the utility model perhaps is equal to replacement, does not all break away from the essence and the scope of the utility model technical scheme.
