Abstract
The utility model relates to arc-free switch equipment, which comprises an arc-free switch with a fixed contact and a movable contact, wherein a positive temperature coefficient (PTC) element bridges connection conductors of the fixed contact and the movable contact which serve as a pair of main contacts. The arc-free switch equipment can replace the conventional arc-free device and has the characteristics of small size, low cost, reliable performance and long service life.
Description
Technical field
The utility model belongs to the high voltage switchgear technical field, relates to a kind of switchgear, especially a kind of Switch without electric arc equipment.
Background technology
The arc-suppressing method of switchgears such as existing circuit breaker, on-load switch, contactor has mechanical means elongation electric arc, magnetic force arc blow-out, vacuum blow-out, the cooling of many sheet metals to cut apart electro-forge, gas-blast, oil gasization and decomposes kinds such as producing arc blow-out, and existing problem is not that volume Peng is exactly greatly that complex structure, cost are big.
The utility model content
The purpose of the utility model is to overcome the shortcoming of above-mentioned prior art, and a kind of Switch without electric arc equipment is provided, and this equipment volume is little, and cost is low, the life-span is long.
The purpose of the utility model solves through following technical scheme:
This Switch without electric arc equipment comprises the Switch without electric arc of fixed contact, moving contact, for cross-over connection on the bonding conductor separately of a pair of main contact wherein the PTC element is arranged with fixed contact and moving contact.
Above-mentioned PTC element is connected with the K switch S of deferred action.
Be connected with the damper rod that passes dampening chamber on the moving contact of the K switch S of above-mentioned deferred action; Be fixed with damping sheet on the damper rod in dampening chamber; The other end of limit Buddhist nun bar is connected in the middle part of spring; The two ends of spring are fixed on the n shape frame of deciliter power rail, and the other end of deciliter power rail links to each other with moving contact through link rod.
The utility model can substitute existing no arc device, has advantages of small volume, the characteristics that cost is low, dependable performance, life-span are long.
