Embodiment
The embodiment of the present invention is described further below in conjunction with the accompanying drawings.Herein it should be noted that for
The explanation of these embodiments is used to help understand the present invention, but does not form limitation of the invention.It is in addition, disclosed below
As long as each embodiment of the invention in involved technical characteristic do not form conflict can each other and be mutually combined.
The present invention is further described with reference to accompanying drawing, person of ordinary skill in the field is preferably implemented the present invention,
A kind of back-up protection device of gapless surge protector of the embodiment of the present invention, including housing 1, the first binding post 2, the second wiring
Terminal 3, circuit plate module 4, electromagnetic switch 5, magnetictrip 6 and handle 7, circuit plate module 4, electromagnetic switch 5 and electromagnetism take off
Button device 6 is arranged in housing 1, and is connected electrically between the first binding post 2 and the second binding post 3, it is characterised in that：Housing
Operating mechanism and conducting system are additionally provided with 1, conducting system includes static contact 8, moving contact 9, wire 10 and support conductive plate
11, one end of support conductive plate 11 is connected with the input of electromagnetic switch 5, and the middle part of moving contact 9 is arranged on support conductive plate 11
The other end, the contact 19 of moving contact 9 electrically connected by wire 10 with support conductive plate 11, static contact 8 and is arranged on housing 1
The first binding post 2 electrically connect；Operating mechanism, which includes manipulating trace 12 and slip, emits 13, manipulate one end of trace 12 with
Handle 7 is connected, and the other end for manipulating trace 12 sets slip to emit 13, is provided with manipulation trace 12 and emits 13 to slip
Stressed compression spring 14 is applied, slip emits 13 one end away from compression spring 14 and offseted with moving contact 9, the contact of static contact 8
The flash barrier 15 that its slip of 13 drives is emitted by slip is provided between 19 and the contact 19 of moving contact 9.
The embodiment of the present invention is provided with receiving flash barrier 15 on housing 1 and slided to limit the path of motion of flash barrier 15
Dynamic chute 16, flash barrier 15 are slidably arranged in chute 16.Emitted in order to which flash barrier 15 is connected into slip on 13, flash barrier 15
13 one end being connected are emitted with slip and are provided with connecting hole 17, and connecting hole 17 is set in slip and emitted on 13；In order to prevent flash barrier 15
Emit from slip and come off on 13, emit 13 in slip is provided with for the spacing axis of guide 18 close to one end of compression spring 14.It is dynamic to touch
First 9 are arranged to V-type, and slip emits 13 and slides on control it is combined and disconnection with static contact 8.
The embodiment of the present invention realizes operation flexible mechanism stabilization, and the slip of the drive operating mechanism of handle 7 emits 13 slip
Moving contact 9 is allowed to leave central supported point under its pressure at right angle.When being moved to the left, moving contact 9 emits 13 in control stick to slip
Pressure lower moving contact 9 is combined conducting with static contact 8, and the sliding force that now slip emits 13 is pressure of the horizontal force in vertical direction
It is little with the lateral thrust displacement of handle 7 under power, therefore apply a less active force with regard to a larger vertical pressure can be obtained
Power, frictional force is smaller, so reaches flexible purpose easy to operate.But emit pressure vertically downward on 13 just sliding
It is different, determined by the size power of compression spring 14, its perpendicular acting is on moving contact 9, so that moving contact 9 and quiet
The contact 19 of contact 8 combines even closer, and because the central supported point of moving contact 9 employs movable line contact fulcrum,
So that combine more perfect in horizontal face between moving contact 9 and the contact 19 of static contact 8.The company of manipulation when meeting proof leakage current
Lever 12 can be slided to the right rapidly, and now slip emits 13 and is in an active force to downslide, manipulates trace 12 in extension spring
Moving contact 9 disconnects rapidly in the presence of active force and inertia force, and opens away from that can reach more than 4.5mm, it is achieved thereby that operation
Flexibly.The features such as reliability is high.
The embodiment of the present invention as much as possible realize the straight conductive principle of high current, because conducting electric current is very huge
(10-100) KA, the time is between 10-50 microseconds.Therefore can not have on the premise of enough conductive cross-sectional area is ensured angle or
Angle is the bigger the better the principle being preferred.Huge eddy current magnetism is formed to avoid, has a strong impact on and damaged this product mechanism
Electric property and mechanical performance.The embodiment of the present invention uses straight-line conductive mode.So alleviate significantly because heavy impulse current is big
Influence of the magnetic field force to mechanism.It is achieved thereby that conducting electric current is big, electromagnetic effect power is small.The features such as mechanism stable.Its key point
The fulcrum of moving contact 9 is also designed on conductive plate as support being pressed against on conductive plate tightly, it is achieved thereby that shunting
To reduce the conducting electric current by wire 10.
The embodiment of the present invention is simple in construction and stably, makees when thunder amplification current electromagnetic pulse produces magnetic field to current-carrying part
When firmly with conductor expansion power (namely magnetic vibrations), to connecting effect of the control link of operating mechanism only to axis direction
Power, but also the cushioning effect of 13 and compression spring 14 is emitted by sliding, the destabilizing factor of operating mechanism is also alleviated significantly,
Phenomena such as particularly malfunctioning de- mouth.
Flash barrier of the embodiment of the present invention 15 is small in design space, the small premise of the clearance between open contacts of movable contact 19 and stationary contact 19
Under, arc current interruption is fast, and anti-discharge to climb electric effect good；Due to devising one between dynamic/static contact 8 with mica or asbestos
Small―gap suture shrink-fit structure between the flash barrier 15 made Deng insulating materials, flash barrier 15 and slip emit 13, makes manipulation trace 12
When being slided to the left, flash barrier 15 is and then preceding mobile, is contacted between the contact 19 of moving contact 9 and the contact 19 of static contact 8 good.
When sliding to the right, that is, disconnecting when manipulating trace 12, flash barrier 15 is acted together in the presence of slip emits 13, and soon
Speed is moved to right between the contact 19 of insertion moving contact 9 and the contact 19 of static contact 8, and electric arc is completely separated, so as to realize in big electricity
Electric arc caused by stream disconnection influences minimum to the contact 19 of moving contact 9 and the contact 19 of static contact 8, substantially increases product
Breaking capacity.More than 3000A disjunction, while after being kept completely separate in the contact 19 of the contact 19 of moving contact 9 and static contact 8,
Insulation, anti-arcing and the effect of anti-tracking are served during 2 sub-high pressure again, alleviates significantly and improves because of line fault and wave
Gush, arrester etc. damage after electric discharge and climb electro ultrafiltration.
Upper and lower, left and right in the present invention correspond to the upper and lower, left and right in accompanying drawing of the present invention, and this description makes in order to easy
Expressed, the innovative point in the present invention is operating mechanism and conducting system, remaining feature and Application No.
201710597341.5 feature it is identical.
Embodiments of the present invention are explained in detail above in association with accompanying drawing, but the invention is not restricted to described implementation
Mode.For a person skilled in the art, in the case where not departing from the principle of the invention and spirit, to these embodiments
A variety of change, modification, replacement and modification are carried out, are still fallen within protection scope of the present invention.
