Description
Technical field
This utility model belongs to breaker technical field, the most just relates to a kind of enhancing chopper disjunction energy
The quick arc-striking structure of power.
Background technology
Chopper is the pith in electrical power distribution apparatus, is mainly used in industrial low-voltage power system, is used for connecing
Electric current in logical and disjunction mains-power circuit and protection circuit and power-supply device from overload, under-voltage, short circuit,
The harm of the faults such as single-phase earthing.
Chopper carries out the function of disjunction and is mainly by being arranged in chopper overload or short circuit current
Arc-chutes complete.When the electric current that breaks down in circuit, and current value exceedes the setting guarantor of intelligent controller
When protecting scope, drive operating mechanism action, make the dynamic and static contact of chopper disconnect rapidly, now dynamic,
Voltage between static contact causes air dielectric electric discharge thus produces high-temperature electric arc.Electric arc causes in combustion
Air themperature in arc-control device steeply rises thus accelerates air ionization.On the other hand, electric arc is at arc-chutes
In magnetic field and hydrodynamic effect promotion under, be separated into multiple short arc by multiple arc grid, rely on metal every
The deionization effect of arc sheet strengthening electric arc, electric arc diminishes and voltage raises rapidly, makes arc extinction.
Existing low-pressure plastic shell circuit breaker, when cutting off circuit, and adds the ablation of quiet silver point to reduce electric arc
Fast electric arc enters arc-chutes, need to control the electric arc time of staying on quiet silver point, drives arc motion at present
Electromagnetic force is provided with arc-chutes by the static contact panel galvanic circle of U-shaped structure or other versions.Static contact panel is wanted
Then it must have certain physical dimension and take up room, if stationary contact hardens to provide stronger electromagnetic force for electric arc
Structure size is little and does not take up space then that it cannot provide stronger electromagnetic force, electric arc stopping on quiet silver point for electric arc
Staying the time will be longer, the ablation to silver point be relatively big, is unfavorable for the disjunction of short circuit current.
Utility model content
When the purpose of this utility model is aiming at existing low-pressure plastic shell circuit breaker cut-out circuit
Arc motion to striking foot speed causes the electric arc time of staying on quiet silver point longer the most slowly
Technological deficiency, it is provided that a kind of quick arc-striking structure strengthening chopper breaking capacity, by quiet
Place a U-shaped magnetic conduction construction below touch panel, enhance striking magnetic field near quiet silver point, accelerate electricity
Arc, by quiet silver point to arc leading angle movement velocity, shortens transit time, thus improves chopper disjunction
Ability.
Technical scheme
In order to realize above-mentioned technical purpose, a kind of of this utility model design strengthens the fast of chopper breaking capacity
Speed arc-striking structure, it includes static contact panel and quiet silver point, it is characterised in that: described static contact panel include conductive part and
Installation portion, quiet silver point is installed on static contact panel, is positioned at the static contact panel below quiet silver point and is increased magnetic sheet parcel.
Further, described conductive part is U-board, and the bottom surface of U-board and side opening are provided with clearance opening, breach
The bore edges in hole stretches out leg, leg and striking foot and is fitted together, and quiet silver point is contained in the head end of leg, increases magnetic
Plate is U-board, increases magnetic sheet and is contained in that leg bottom surface is upper can extend to striking underfooting side below quiet silver point,
U-shaped increases the dual-side of magnetic sheet and is positioned at quiet silver point both sides.
Further, described striking foot upper surface is not less than leg upper surface.
Further, described increasing magnetic sheet is L-shaped or double L-shaped.
Beneficial effect
A kind of quick arc-striking structure strengthening chopper breaking capacity that this utility model provides, by stationary contact
