Description

A kind of RCCB

Technical field

A kind of RCCB is the utility model is related to, 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, it is reasonable that the utility model provides a kind of internal space layout, compact-sized, Mechanism kinematic is flexible, the fast new RCCB of breaking speed.

Above-mentioned purpose is realized, the technical solution adopted in the utility model is：A kind of RCCB, include base, in Seat and upper lid, middle seat are the first installing space, middle seat and upper lid between base and upper lid, between its center base and middle seat Between be the second installing space, be the 3rd installing space between base and upper lid, be provided with that N is extremely dynamic to be touched in first installing space Head operating mechanism and N poles arc-extinguishing mechanism, L poles moving contact operating mechanism, L poles arc-extinguishing mechanism are provided with second installing space With bimetallic tripping mechanism, electric leakage magnet ring and electric leakage, short-circuit tripping mechanism and handle behaviour are provided with the 3rd installing space Make mechanism, 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 this Recess, the handle operation mechanism side are provided with experiment press device, and experiment press device includes button, torsion spring, led Electric piece and loose piece, torsion spring include the first adjutage and the second adjutage, and torsion spring is arranged on the bearing pin of base, and the first of torsion spring Adjutage is placed in below button, and is realized and swung up and down so as to realize that contact with conducting strip or disconnection are matched somebody with somebody with the pressing of button Close, the loose piece is arranged on base by axle, loose piece include upper side, downside, bottom surface, upper surface, left surface and Right flank, 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 The side of face, one of face and base contradicts or presses close to set, and another face contradicts with conducting strip or presses close to set and realizes to leading Electric piece 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 in the shoulder On 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 under limit button Pressure amplitude 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.

It is of the present utility model further set be：Electricity-fetching mechanism, power taking machine are additionally provided with the side of handle operation mechanism Structure includes power taking post or power taking spring and slides the push rod being arranged on base, and one end and the N poles moving contact of the push rod are grasped The moving contact for making mechanism is hinged swinging end and coordinated, and the second adjutage of the other end and torsion spring, which contradicts, to be coordinated, and the power taking post or takes Electrical 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 When, the 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 is grasped When making 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 Swing realizes 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.
