Abstract
The utility model discloses a kind of ring main unit load switch, it is related to electrical equipment, the static contact of the ring main unit load switch electrically connects with the binding post of hull outside, and enclosure interior is movably equipped with moving contact, moving contact is externally connected to control stick, and housing side is provided with some arc extinguishing passages.The ring main unit load switch can be connected to during installation in ring main unit circuit by binding post and control stick, control stick connects control device, control stick promotes moving contact, and the ring main unit load switch is in an ON state when being contacted with static contact, when control stick pulls moving contact to be separated with static contact, electric arc can be produced between moving contact and static contact, and because moving contact and inner walls are fitted close, air can be blown into housing from arc extinguishing passage, by arc extinction, the ring main unit load switch is in an ON state.The ring main unit load switch designs compact, simple and practical, small volume, is adapted to use in ring main unit.
Description
Technical field
Electrical equipment is the utility model is related to, relates in particular to a kind of ring main unit load switch.
Background technology
Ring main unit is exactly that each distribution branch road sets an outlet switch cabinet, and the bus of this switch cubicle is exactly that annular is dry simultaneously
A part for line.Because the rated current of ring main unit is little, the high-voltage switch gear in ring main unit is usually on-load switch.It is existing negative
Lotus switch designs are complicated, cause volume too big, are not suitable for using in compact and compact ring main unit.
Utility model content
For the utility model mainly solving the technical problems that providing a kind of ring main unit load switch, design is compact, simple real
With small volume, being adapted to use in ring main unit.
To achieve the above object, the utility model provides following technical scheme：The ring main unit load switch includes one end
The housing of opening, the closed end inside of housing are provided with static contact, and static contact electrically connects with the binding post of hull outside, in housing
Portion is movably equipped with moving contact, and moving contact is externally connected to control stick, and housing side is provided with some arc extinguishing passages, arc extinguishing passage
It is respectively positioned on the link position of moving contact and static contact.
As the further optimization of the technical program, the housing is manufactured by insulating plastics material.
As the further optimization of the technical program, the static contact, moving contact, binding post, control stick close by copper
Gold manufacture, moving contact are fitted close with inner walls.
Beneficial effect using above technical scheme is：The static contact of the ring main unit load switch and the wiring of hull outside
Terminal electrically connects, and enclosure interior is movably equipped with moving contact, and moving contact is externally connected to control stick, and housing side is provided with some arc extinguishings
Passage.The ring main unit load switch can be connected in ring main unit circuit by binding post and control stick, manipulated during installation
Bar connects control device, control stick promote moving contact when being contacted with static contact the ring main unit load switch in an ON state, when
Control stick pulls moving contact to be separated with static contact, and electric arc can be produced between moving contact and static contact, and due to moving contact and housing
Inwall is fitted close, and air can be blown into housing from arc extinguishing passage, and by arc extinction, the ring main unit load switch, which is in, to be connected
State.The ring main unit load switch designs compact, simple and practical, small volume, is adapted to use in ring main unit.
Brief description of the drawings
Specific embodiment of the present utility model is described in further detail below in conjunction with the accompanying drawings.
Fig. 1 is structure sectional view when a kind of ring main unit load switch of the utility model closes；
Fig. 2 is structure sectional view when a kind of ring main unit load switch of the utility model disconnects.
Wherein, 1-housing, 2-static contact, 3-moving contact, 4-binding post, 5-control stick, 6-arc extinguishing passage.
Embodiment
Illustrate a kind of preferred embodiment of ring main unit load switch of the utility model below in conjunction with the accompanying drawings.
Fig. 1 and Fig. 2 shows a kind of embodiment of ring main unit load switch of the utility model：
With reference to Fig. 1 and Fig. 2, the ring main unit load switch includes the housing 1 of one end open, is set inside the closed end of housing 1
There is static contact 2, static contact 2 electrically connects with the binding post 4 outside housing 1, and the internal activity of housing 1 is provided with moving contact 3, moving contact
3 are externally connected to control stick 5, and the side of housing 1 is provided with some arc extinguishing passages 6, and arc extinguishing passage 6 is respectively positioned on moving contact 3 and quiet
The link position of contact 2.
Housing 1 is manufactured by insulating plastics material, sturdy and durable, and insulating properties is good.Static contact 2, moving contact 3, terminals
Son 4, control stick 5 are manufactured by copper alloy, and electric conductivity is good, and moving contact 3 is fitted close with the inwall of housing 1.
The ring main unit load switch can be connected the ring main unit load switch by binding post 4 and control stick 5 when mounted
It is connected in ring main unit circuit, control stick 5 connects control device.As shown in figure 1, control stick 5 promotes moving contact 3 to be connect with static contact 2
Pulls moving contact 3 to be separated with static contact 2 to the ring main unit load switch as shown in Fig. 2 working as control stick 5 in an ON state when touching,
Electric arc can be produced between moving contact 3 and static contact 2, and because moving contact 3 and the inwall of housing 1 are fitted close, air can be from arc extinguishing
Passage 6 is blown into housing 1, arc extinction, arc quenching effect is good.The ring main unit load switch is in an ON state.Control stick
5 promote moving contact 3 again, and the air between moving contact 3 and static contact 2 can be blown out from arc extinguishing passage 6 when being combined with static contact 2
Outside housing 1, flexibility and reliability is operated.Ring main unit load switch design is compact, simple and practical, small volume, is adapted in ring main unit
Middle use.
The above is only preferred embodiment of the present utility model, it is noted that for one of ordinary skill in the art
For, on the premise of not departing from the utility model and creating design, various modifications and improvements can be made, these belong to this
The protection domain of utility model.
