Description
Technical field
The present invention relates to a kind of vacuum switches for being mainly used for the fields such as electrical equipment, Electric control, more particularly to one kind
Permanent magnetic drive type vacuum switch.
Background technique
Vacuum switch is a kind of switch being placed in make break contact in the vacuum lumen of vacuum warehouse, also referred to as vacuum contactor
Or vacuum circuit breaker, compared to antivacuum switch there is automatic arc-suppression function will not generate electric arc because not having air in vacuum.
Traditional vacuum switch, there are mainly two types of the closures and separation control of contact, and one is control by mechanical-force-transmission
Movable contact movement, another kind are by magnetic transmission control movable contact movement;The former due to necessarily have transmission mechanism pass through vacuum warehouse,
And transmission mechanism can move, so easilying lead to poorly sealed, air is easily accessible vacuum warehouse, causes to lose vacuum extinction
Function, and there are also drive mechanisms it is complicated, volume is larger the defects of, such as Patent No. " ZL 201520801050.X ", title
A kind of utility model patent for " monopole vacuum switch " there is the above problem;The latter passes through very due to not needing transmission mechanism
Hole capital after selling all securities, so the above problem is not present.It therefore, is device more advanced at present using the vacuum switch of magnetic control open and close.
But the existing vacuum switch using magnetic control open and close, there are magnetic pole distributions not to concentrate, volume is big, magnetic force is small
The problems such as, it is unfavorable for the miniaturization of vacuum switch, the reliability of switch control is insufficient, keeps its application limited.
Such as the patent of invention of Patent No. " ZL 200710141473.3 ", disclose a kind of vacuum touching of permanent magnetism control
Point switch, including shell, stationary contact, movable contact, moving contact support, moving contact support sliding block, moving contact support sliding block slideway,
Vacuum-pumping tube, capping, the magnet on the left of moving contact support, left side move the magnet on magnetic receiver, and left side moves magnetic receiver,
Magnet on the right side of moving contact support, right side move the magnet on magnetic receiver, and right side moves magnetic receiver.The magnetic of the vacuum switch
Pole is respectively provided at vacuum tube both ends, cannot concentrate in together, and causes loosely organized, and volume is larger, and needed using magnet it is larger,
The too small magnetic force of magnet is inadequate, be easy to cause contact force insufficient, makes heating of contact, additionally, due to the influence of vacuum casting, make
The reduced capability of magnetic attraction and disjunction, contact disjunction stroke reduce, and also reduce the reliability of switch control.
In addition, there is also drive mechanism either complexity or insecure problems for traditional vacuum switch, increase its volume
Or operation is unreliable, affects the operating characteristics of vacuum switch.
Summary of the invention
The object of the invention is that solve the above-mentioned problems and provide a kind of structure concentrate, small volume and switch control
Make reliable permanent magnetic drive type vacuum switch.
The present invention through the following technical solutions to achieve the above objectives:
A kind of permanent magnetic drive type vacuum switch, including switch housing body, operation handle, transmission device, active permanent magnet, vacuum
Storehouse, passive permanent magnet, movable contact, stationary contact and connecting terminal, the operation handle outside the switch housing are mounted on
It is connect on the switch housing body and by the transmission device with the active permanent magnet, the active permanent magnet and described true
