Description
Technical field
The present invention relates to control with protection switch electrical equipment in release, be specifically related to the transmission mechanism in a kind of release.
Background technology
Control is a kind of existing on-off action with protection switch electrical equipment, can carry out the electrical equipment of decompression, under-voltage, overload and open circuit protection again automatically.Power circuit and motor etc. are carried out protection, can automatic shutdown circuit when serious overload or short circuit and fault such as under-voltage take place for they.
Disclose a kind of integrated control and protection switch electrical equipment like existing patent documentation CN2472341Y, it comprises base, main circuit contact group, and electromagnetism transmission mechanism, operating mechanism, interrupter, overcurrent trip, interlocking device, power supply detect relay.The differential attachment of the overcurrent release upper guide plate and the bottom guide that have respectively three bimetal leafs that are in series with power supply three and driven by bimetal leaf wherein.In above-mentioned control and the protection switch electrical equipment, under the situation of three-phase overload, the heating of bimetal leaf heated element; It is crooked left to promote upper guide plate, promotes push pedal and makes the transmission mechanism action, and the slurcam in the overcurrent release is moved; Slurcam promotes the push rod of operating mechanism, realizes overlond trip; When the circuit phase failure; Phase failure bimetal leaf will cool off then crooked to the right, promote bottom guide and move to right, and other two bimetallic sheets still make upper guide plate move to left under the situation of current flow heats; The result is rotated counterclockwise slurcam under last bottom guide promotes; Make the transmission mechanism action rapidly and slurcam is moved, slurcam promotes the push rod in the operating mechanism, realizes differential phase failure dropout.
And this mode can't satisfy the instructions for use of some special occasions; For example stipulated in " civil buildings electrical design standard " that sudden power will cause than the bigger motor of overload loss; Should not install overload protection; When distribution line is in overload, only send alarm signal, do not send trip signal and force outage.Such as unpredictalbe fault of distribution line and the emergency starting of fire pump during fire in the fire-fighting system; All may cause the appearance of transshipping; In order to win the quality time of handling failure; Should not be in the overload situations dropout down that this fault level causes, make the staff to make judgement and decision accordingly according to on-the-spot at that time special circumstances but need send alarm signal.Therefore in some special occasions, control and protection switch electrical equipment will be implemented in following function of reporting to the police and not threading off of situation of overload.
Solve the problems of the technologies described above, need overcurrent release can be implemented in the action that can realize warning function under the overload and the situation of the phase failure, and operating mechanism can have the action of relative trigger alarm signal at overcurrent release generation actuation of an alarm.
In order to solve the problems of the technologies described above; The applicant has applied for one piece of control and operating mechanism of protection switch electrical equipment of being disclosed on the patent documentation CN102427000A in 2011; When overload fault occurring, overload is threaded off by overload push rod control warning cam and is given the alarm; When over current fault occurring, the overcurrent push rod drives the overload push rod all moves warning cam and deflecting cam, and the warning cam is threaded off and given the alarm and deflecting cam dropout cut-out main circuit.Operating mechanism in this scheme can be implemented in an alarm non-tripping under the situation of overload, under the situation of overcurrent, exports trip signal.This operating mechanism will be worked normally, and the overcurrent release that need be mated can give the overload push rod impulsive force when overload, when overcurrent, gives impulsive force of overcurrent push rod.
For this reason, the applicant has submitted another piece patent application " the signal transport sector of overcurrent trip " July 27 in 2012 to State Intellectual Property Office, and application number is CN201220370230.3, and it comprises differential attachment, alarm mechanism and delayed releasing mechanism.Differential attachment comprises differential plate and guide plate, and guide plate is parallel and be arranged at the side of differential plate movably, and differential plate is connected with bimetal leaf with guide plate and under the driving of bimetal leaf, moves, and bimetal leaf is connected with the power supply three-phase line; Alarm mechanism is arranged on the support that is positioned at differential attachment one side, and alarm mechanism cooperates the transmission alarm signal with guide plate; Delayed releasing mechanism is arranged on the support, cooperates with guide plate to transmit trip signal; The alarm actuating contact of guide plate and alarm mechanism contact contacting early than the dropout contact of guide plate and delayed releasing mechanism.In such scheme, alarm mechanism comprises first rocking arm that is used to transmit alarm signal, comprises second rocking arm and the dropout rocking arm that are used to transmit trip signal in the delayed releasing mechanism.Though said structure can be through first rocking arm transmission alarm signal; Through dropout rocking arm transmission trip signal; But because first rocking arm and dropout rocking arm all are to move under the driving after sheet metal is heated; Be a kind of simple interaction relation, the power of its output is less, and the overload push rod of operating mechanism and overcurrent push rod need bigger impulsive force ability operate as normal; Therefore first rocking arm and dropout rocking arm do not have enough impulsive forces when transmission alarm signal trip signal; If simple is used disclosed operating mechanism among signal transport sector in the such scheme and the CN102427000 A, when overload signal occurring, overload push rod and then the dropout of control warning cam that the power that first rocking arm produces is not enough to promote in the operating mechanism give the alarm; When over-current signal occurring, the power that the dropout rocking arm produces also is not enough to drive overcurrent push rod drive overload push rod all moves warning cam and deflecting cam.
Therefore, in overcurrent release, also needing transmission mechanism transmits the alarm signal of above-mentioned signal transport sector transmission and trip signal and amplifies.And overcurrent release of the prior art owing to all do not consider the function of following alarm non-tripping of overload situations, therefore can only all be exported overload signal and over-current signal at the transmission mechanism of set inside through a push rod.Like disclosed overcurrent release among the CN2472341Y, no matter be that overload or overcurrent take place, its transmission mechanism finally all is to move to the operating mechanism transfer instruction through a push rod.
Therefore the transmission mechanism in the prior art release can not cooperate with signal transport sector and operating mechanism, can't first rocking arm of signal transport sector and the power and the displacement of dropout rocking arm transmission be amplified the overload push rod and the overcurrent push rod of back trigger action mechanism.
Summary of the invention
Technical problem to be solved by this invention is that the transmission mechanism in the release can't amplify the overload push rod of back trigger action mechanism and the technical problem of overcurrent push rod with displacement with the power of first rocking arm of signal transport sector and the transmission of dropout rocking arm in the prior art, and then a kind of first rocking arm of effectively amplifying signal transport sector and power that the dropout rocking arm transmits and displacement is provided and the transmission mechanism of the release that can cooperate with operating mechanism.
