Abstract
The utility model belongs to the field of switching apparatuses, particularly relates to an arc-extinguishing switch in a high-voltage circuit, and discloses an insulating oil arc-extinguishing button switch, which comprises a button locking mechanism (1), a button spring (2), a moving contact (3), a static contact (4) and an outer casing (5), the periphery and the bottom of a space (6) holding the moving contact (3) and the static contact (4) in the outer casing (5) are both sealed, insulating oil (7) is filled in the space (6), and the static contact (4) is immersed in the insulating oil (7). The insulating oil arc-extinguishing button switch holds the insulating oil inside, the static contact is immersed by the insulating oil, and when the moving contact contacts with the static contact to generate electric arcs, the electric arcs are cooled and extinguished by the insulating oil, thereby guaranteeing the switch against being broken down, leading the switch to be more stable during usage, and prolonging the service life of the switch.
Description
Technical field
The utility model belongs to the device for switching field, particularly relates to the arc-suppressing switch in a kind of high-tension circuit.
Background technology
In high voltage supply in the various device for switching such as used circuit breaker, contactor, it is very big when switch operates owing to voltage jump, so the voltage between the contact can cause the air dielectric discharge, form high-temperature electric arc, in the electric arc forming process, the energy that is discharged by Joule effect is very high, be easy to burn out metal, switch is melted together, make switch scrap, significantly reduced the useful life of switch, the meeting glow switch is on fire in the time of serious, so all need special arc-control device to come extinguish arcs usually, to guarantee the electric equipment security of operation; Existing arc-control device is to adopt arc control device mostly, and electric arc is introduced arc control device, absorbs electric arc with isoionic gaseous material, realizes the effect of arc extinguishing.Though the method effect of this arc extinguishing is fine, complex structure, when design standard improves such as wanting that by 5KV 10 seconds high pressure just needs the arc control device of significant volume when detecting, cost is very high, is unfavorable for using in general common place.
Summary of the invention
Technical problem to be solved in the utility model provides a kind of insulating oil arc extinguishing push-button switch, utilizes insulating oil cooling extinguish arcs, the useful life of having improved switch.
A kind of insulating oil arc extinguishing push-button switch, comprise button locking mechanism, button spring, moving contact, fixed contact and shell, described fixed contact matches with moving contact, fixed contact is fixing in the enclosure, moving contact is installed in the enclosure by movable contact spring, and moving contact is driven by movable contact spring has the second place that contacts primary importance and be separated with fixed contact with fixed contact; Described button spring has two, be arranged in the upper and lower surface of movable contact spring, one of them button spring is installed on the button locking mechanism, another is installed in shell, the restoring force of button spring helps moving contact to be returned to the second place from primary importance, in the described shell, be furnished with moving contact and fixed contact the space around and the bottom all be hermetically-sealed construction, be filled with insulating oil in this space, described fixed contact is immersed in the insulating oil.
With the sealing ring sealing, outer casing bottom also seals with sealing ring with the opening part of the binding post that moving contact links to each other with fixed contact around the space of described shell lower inner.
The top in described space has a button spring through hole.
Beneficial effect
The utility model volume is little, and is simple in structure, only needs in the enclosure portion to install insulating oil additional and gets final product; Fixed contact is insulated oil immersion not to be had, and when the sound contact contacted generation electric arc, electric arc was insulated oil cooling and but extinguishes, and guarantees that switch is not breakdown, makes switch more stable when in use, the useful life of having improved switch.
Description of drawings
Fig. 1 is the structural representation of the utility model insulating oil arc extinguishing push-button switch;
Fig. 2 is the end view of Fig. 1.
Among the figure: 1 button locking mechanism, 2 button spring, 3 moving contacts, 4 fixed contacts, 5 shells, 6 movable contact springs, 6 seal cavities, 61 sealing rings, 7 insulating oils, 8 binding posts.
Embodiment
Below in conjunction with specific embodiment, further set forth the utility model.Should be understood that these embodiment only to be used to the utility model is described and be not used in the restriction scope of the present utility model.Should be understood that in addition those skilled in the art can make various changes or modifications the utility model after the content of having read the utility model instruction, these equivalent form of values fall within the application's appended claims institute restricted portion equally.
As shown in Figure 1, 2, a kind of insulating oil arc extinguishing push-button switch, comprise button locking mechanism 1, button spring 2, moving contact 3, fixed contact 4 and shell 5, described fixed contact 4 matches with moving contact 3, fixed contact 4 is fixed in the shell 5, moving contact 3 is installed in the shell 5 by movable contact spring 6, and moving contact 3 is driven by movable contact spring 6 has the second place that contacts primary importance and be separated with fixed contact 4 with fixed contact 4; Described button spring 2 has two, be arranged in the upper and lower surface of movable contact spring 6, one of them button spring 2 is installed on the button locking mechanism 1, another is installed in shell 5, the restoring force of button spring 2 helps moving contact 3 to be returned to the second place from primary importance, in the described shell 5, be furnished with moving contact 3 and fixed contact 4 space 6 around and the bottom all be hermetically-sealed construction, be filled with insulating oil 7 in this space 6, described fixed contact 4 is immersed in the insulating oil 7; The top in described space (6) has a button spring through hole.
What need in the present embodiment to further specify is, described hermetically-sealed construction be around the space of described shell 5 lower inner with sealing ring 61 sealings, shell 1 bottom also seals with sealing ring 61 with the opening part of the binding post 8 that moving contact 3 links to each other with fixed contact 4.
The utility model is because only be to charge into insulating oil in the inside of shell 5, thus can not increase the volume of switch, simple in structure; In use, as required, can all be full of insulating oil to inside, also can only allow insulating oil just cover fixed contact 4, when the temperature of arc discharge is very high, can the be heated tapping of from the space 6 ceiling button springs 2 of shell 5 gas inside is run out of, and can not cause danger, and insulating oil can not leak yet.
