The axis of described return spring 20 with the axis of contact spring 24 on the same line, makes return spring 20 exist
Deflection will not be produced because of deviation contact spring 24 during decline, make quiet contact chip 5 contact reliable and stable with moving contacting plate 22.
All to weld between described coil tube 11 and base 2, between shell 3 and base 2, between quiet contact chip 5 and shell 3
Fixing connection；Assemble and have two assembly holes 9 on shell 6, utilize Lengthened bolt to be clamped by shell 3 from front and back.
Described insulation flash barrier 26 for sawtooth sector structure and is evenly arranged in arc-extinguish chamber to moving contacting plate 22 in enclosed
Housing 28 inwall, magnetic blow-out system 23 electric arc is blowed to insulate flash barrier 26 top, this interprocedual increase electric arc with insulation every
The contact area on arc grid 26 surface, thus strengthen cooling and the deionization of electric arc, promote the extinguishing of electric arc.
Stationary contact 30, described moving contacting plate 22 two ends outer surface it is equipped with on the extrados of described two panels quiet contact chip 5 top
On be equipped with movable contact 29；This dynamic contact point 29 on same vertical direction, moves contact point 29 and stationary contact 30 with stationary contact 30
Laying respectively at the upper surface geometric center position of moving contacting plate 22 and quiet contact chip 5, this dynamic contact point 29 is in stationary contact 30
To guarantee that moving contacting plate 22 and quiet contact chip 5 can be fitted comprehensively on same vertical direction, increase two contact chip contacts to greatest extent
Area.
Described contact monomer assembly is most preferably preferably three normally opened contact monomers 1 and forms, at this moment pushing mechanism iron core 17
In middle normally opened contact monomer 1 position directly below, with the stressing conditions of two normally open contactor monomers 1 before and after equilibrium.
Fine motion sheet switch 7 is provided with Magnet, fine motion sheet switch 7 connection magnetic blow-out system 23, connects when circuit and produces magnetic field, micro-
Moving plate switch 7 also concomitant rotation, i.e. master worker can know whether circuit is connected from the outside.
Workflow and principle:
Base 2 of the present invention is installed on Transit Equipment, more some direct current transmission line two ends are respectively connected to two
On quiet contact chip 5, the through a DC stream on bobbin 12, make the coil generating electromagnetic field on bobbin 12, thus attract
Iron core 17, iron core 17 pulls the promotion plate 18 of top to pull downwards motion, then promotes plate 18 to drive gearing frame 31 to transport downwards
Dynamic, interlock frame 31 and move downward, the moving contacting plate 22 being provided at its inner portion on the contact spring 24 on top and spring is transported downwards
Dynamic so that it is being fitted on quiet contact chip 5, contact spring 24 alleviates moving contacting plate 22 and down moves to contact on quiet contact chip 5
Collision, thus connect DC circuit circuit, when DC line closed by needs, the electric current that will lead on bobbin 12 disconnects,
Electromagnetic field on bobbin 12 disappears, and under the effect of return spring 20, moving contacting plate 22 quickly resets, and moving contacting plate 22 is with quiet
Contact chip 5 disconnects, and disconnecting with the DC line on quiet contact chip 5 so that connecing, playing and utilizing Small current control HVDC
Effect, facilitates safer, produces temperature at contact point be at that moment up to when quiet contact chip 5 contacts with moving contacting plate 22 or disconnects
The electric arc of about 2000 °, on catalyst impact and destroy relatively big, the magnetic blow-out system 23 of the present invention uses the power on moment and can produce magnetic
, and electric arc is under the influence of a magnetic field, the principle that can be elongated rapidly, produces magnetic field in energising moment and electric arc is blown into arc extinguishing
In cover 4, electric arc elongates generation arc drop value to be increased the most accordingly, and during arc drop >=supply voltage, making loop current is zero, reaches
To the effect of arc extinction, it is substantially reduced electric arc to the destruction of part in catalyst, the service life of raising catalyst.
Arc quenching principle:
With two identical mutual snap closes of arc-extinguish chamber housing 28, form arc-chutes, and be provided with in arc-chutes 2 quiet
Arc striking piece 21 and 1 dynamic arc striking piece 25 and be metal material, working is: under product is in action of high voltage, dynamic at product,
When stationary contact is opened and disconnects, air breakdown can be made, produce electric arc, because arc quenching system sets at the dynamic and static contact position of product
Meter, according to left hand rule principle, carries out magnetic quenching to product contact when electric current moves in magnetic field, and its magnetic blow-out mode is band
Point ion is by Lorentz force action direction, and electric arc, under magnetic blow-out effect, makes electric arc elongate, and the effect of elongation has two: 1. make electricity
Arc elongates the cut-out intracavity in arc-extinguish chamber, makes electric arc segmentation disconnect, and cools down arc extinguishing；2. another effect is to be drawn by the electric arc of burning
Long, make arc drop increase, electric arc often elongates 1 inch of arc drop value produced and is about 25V, public according to arc through voltage
Formula: IR=U (supply voltage)-ε (arc drop total value), according to formula, when arc drop total value exceedes supply voltage value, IR
Value is negative value, illustrates that the electric current breakdown value in loop is zero, i.e. loop breakdown, and loop current flows to: the quiet contact chip of product 5 (produces
Product positive source) → quiet arc striking piece 21 → air arc (particle) → dynamic arc striking piece 25 → air arc (particle) → quiet arc striking piece
The quiet contact chip of 21 → product (product power cathode) → load → power supply is born, and forms loop.Current value in loop is zero, does not has
Electric current flows through, and will not produce electric arc, reaches the effect of arc extinguishing.This process is the time of tens milliseconds.And then reach arc extinguishing
Effect.Thus it is impaired to protect product contact, improve catalyst physical life.
