Abstract
A safe power switch relates to the power switch field. The invention especially relates to the safe power switch which does not use an insulating oil, is without vacuum and uses a solid medium to isolate air and carry out arc suppression. The invention designs the safe power switch which uses the solid medium to isolate air and carry out arc suppression. A technical scheme is characterized in that the safe power switch is mainly formed by a moving block medium, a moving contact, a static block medium and a static contact; the moving contact is arranged in the moving block medium; the static contact is placed into the static block medium; a contact surface of the moving block medium and the static block medium is a smooth plane and the moving block medium and the static block medium can slide relatively; the moving block medium presses the static block medium lightly and the air is removed so as to eliminate arc; the moving block medium is moved along the contact surface; the moving contact is moved along with the moving block medium so as to switch on and off of the circuit. The switch has the advantage that during a process of switching the on and off of the circuit, there is no air between the moving contact and the static contact so that the arc is not generated.
Description
Technical field
The present invention relates to power switch field, particularly a kind of security power switch.
Background technology
Power switch is the basic controlling element of electric power system, and its effect is commutation circuit break-make.When switching, traditional power switch meeting ionized air, produces electric arc, burns out equipment, burn burn personnel to death.Therefore, interception and elimination electric arc are the cruxs of power switch.Overcome electric arc to cause harm and mainly contain two kinds of methods: interception electric arc and isolated air extinguishing arc.Metal grid can tackle electric arc, but galvanic corrosion can reduce and blocks arc effect.Isolated air tradition has two kinds of methods: insulation oil process and vacuum method.Insulating oil extinguishing arc, complex structure, fault point is many.Vacuum method extinguishing arc, if any gas leakage, the danger that vacuum chamber has electric arc to explode.
Summary of the invention
In order to improve the fail safe of commutation circuit, the present invention designs a kind of security power switch.
The present invention realizes the technical scheme that goal of the invention adopts: security power switch by motion block, quiet piece, moving contact, fixed contact, wide shell fragment, terminal block, hole seven part form.
Moving contact is placed in motion block medium.Fixed contact puts into the hole of quiet piece of medium.The contact-making surface of motion block and quiet piece is smooth flat, can relative sliding.Motion block gently presses quiet piece, arranges air, to eliminate electric arc.Move motion block medium along contact-making surface, moving contact follower block moves, commutation circuit break-make.Be connected with wide shell fragment between wiring place with fixed contact.When channel status, wide shell fragment makes fixed contact gently press contact.Make the two contact good.
The invention has the beneficial effects as follows: provide a kind of and do not vacuumize without insulating oil, use solid dielectric to completely cut off the power switch of air extinguishing arc, structure is simple, safe and reliable.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the invention will be further described.
Fig. 1 is security power on-off principle schematic diagram.
In FIG, 1. motion block, 2. moving contact, 3. quiet piece, 4. fixed contact, 5. wide shell fragment, 6. terminal block, 7. hole.
Embodiment
Motion block (1) and quiet piece (3) manufacture with insulating material.Moving contact (2), fixed contact (4), wide shell fragment (5), terminal block (6) manufacture with conductor.Moving contact (2) is placed in motion block (1), and fixed contact (4) is placed in the hole (7) of quiet piece (3).Be connected with wide shell fragment (5) between terminal block (6) with fixed contact (4).When channel status, wide shell fragment (5) makes fixed contact (4) gently press contact (2).Make the two contact good.Motion block (1) is smooth flat with the contact-making surface of quiet piece (3), can relative sliding.Motion block (1) is pressure quiet piece (3) gently, arrange air, to eliminate electric arc.Vertically or mobile motion block perpendicular to axial direction (1), moving contact (2) follower block (1) is mobile, commutation circuit break-make.
