Description
Technical field
The present invention relates to a kind of RCCB, particularly relates to the compact RCCB of reasonable in internal structure.
Background technology
RCCB is typically provided with magnetictrip, thermal trip, leakage tripping device, operating mechanism, arc extinguishing passage
And arc quenching system, in general RCCB are to increase board space by lengthening or add wide way on the basis of breaker
Or leakage tripping device space, cause small product size big, cost is high, and installation cost is high, assembles the shortcomings of distribution box volume is big, generally
RCCB its internal space layout, typically in the following ways, L poles, N poles moving contact is separately fixed at L poles, N poles
On moving contact rack, then L poles, N poles moving contact rack are arranged on the both sides of lever, and lock and tripping are also disposed on lever,
Now organization volume is big, and mechanism kinematic is dumb, and breaking speed is slow, and L poles, N poles moving contact are located at the both sides of middle seat respectively, because of L
Pole, N poles moving contact rack are arranged on the both sides of lever, and mechanism section L poles can not isolate with N poles, during disjunction high current electric arc and
The easy short circuit of gaseous conductor, which causes product to burst, makes product disjunction fail.And the risk of pressure-resistant breakdown after disjunction be present, and L
Pole arc-chutes are smaller, and N is extremely typically not provided with arc-chutes, therefore product breaking capacity is low, it is impossible to meets user's requirement.
The content of the invention
For overcome the deficiencies in the prior art, the invention provides a kind of internal space layout is reasonable, compact-sized, mechanism
Motion is flexible, the fast new RCCB of breaking speed.
Above-mentioned purpose is realized, the technical solution adopted by the present invention is：A kind of RCCB, include base, middle seat and
Upper lid, middle seat are the first installing space between its center base and middle seat, are between middle seat and upper lid between base and upper lid
Second installing space, it is the 3rd installing space between base and upper lid, N poles moving contact behaviour is provided with first installing space
Make mechanism and N poles arc-extinguishing mechanism, L poles moving contact operating mechanism, L poles arc-extinguishing mechanism and double are provided with second installing space
Metal dropout mechanism, electric leakage magnet ring and electric leakage, short-circuit tripping mechanism and handle operation machine are provided with the 3rd installing space
Structure, it is characterised in that：Be in depression setting on the middle seat and at the arc-extinguishing mechanism of L poles, and L poles arc-extinguishing mechanism is arranged on the depression
Place, the handle operation mechanism side are provided with experiment press device, and experiment press device includes button, torsion spring, conducting strip
And loose piece, torsion spring include the first adjutage and the second adjutage, torsion spring is arranged on the bearing pin of base, the first extension of torsion spring
Arm is placed in below button, and is swung up and down with the pressing realization of button so as to realize the contact with conducting strip or disconnect cooperation, institute
State loose piece to be arranged on base by axle, loose piece includes upper side, downside, bottom surface, upper surface, left surface and right side
Face, the upper side, downside contradict with the side of base respectively or press close to set, and the left surface height is provided with two faces,
One of face and the side of base contradict or press close to set, and another face contradicts with conducting strip or presses close to set and realizes to conducting strip
It is spacing, be provided with shoulder rank on the upper surface, a collision arm of the handle torsion spring of handle operation mechanism is contradicted on the shoulder rank,
Positive stop lug boss is provided with the bottom surface, the conflict pin of the positive stop lug boss and button is correspondingly arranged the lower pressure amplitude of limit button
Degree.
By using such scheme, we make the breaker structure simple, rationally distributed, are in particular in breaker two layers
The function of L poles arc-extinguishing mechanism is had no effect on after layout, experiment press device uses aforesaid way, only passes through one part reality of loose piece
Many functions are showed, spacing, conducting strip positioning, the conflict of handle torsion spring of such as button are described so to make whole open circuit
Mechanism inside device enormously simplify.
The further setting of the present invention is：Electricity-fetching mechanism, electricity-fetching mechanism bag are additionally provided with the side of handle operation mechanism
Include power taking post or power taking spring and slide the push rod being arranged on base, one end and the N poles moving contact operation machine of the push rod
The moving contact of structure is hinged swinging end and coordinated, and the second adjutage of the other end and torsion spring, which contradicts, to be coordinated, the power taking post or power taking bullet
Spring electrically connects with the L poles moving contact of L poles moving contact operating mechanism, when the N poles switch on of moving contact of N poles moving contact operating mechanism,
Second adjutage promotes push rod movement to realize that the second adjutage electrically connects with power taking post or power taking spring, when N poles moving contact operates
During the N poles moving contact separating brake of mechanism, the be hinged swinging end of N poles moving contact promotes push rod movement, and push rod promotes the second adjutage pendulum
It is dynamic to realize that the second adjutage disconnects with power taking post or power taking spring.
By using aforesaid way power taking, we can be realized by the cooperation of N poles moving contact, push rod and torsion spring and turned round very well
The power taking of spring, concrete principle are, when L poles switch on of moving contact, the second adjutage promote push rod movement realize the second adjutage with
Power taking post or power taking spring electrically connect, and the electric can on the moving contact of such L poles is transmitted to torsion by power taking post or power taking spring
On spring, when N poles moving contact separating brake, the be hinged swinging end of N poles moving contact promotes push rod movement, and push rod promotes the second adjutage pendulum
Dynamic to realize that the second adjutage disconnects with power taking post or power taking spring, for torsion spring with regard to not charged, that we need to declare here is L extremely dynamic
Contact and being opened or closed for N poles moving contact are to be mutually related.
The further setting of the present invention is：It is extremely dynamic that the L poles moving contact operating mechanism includes L poles moving contact, tripping, L
