Description

Intelligent no power consumption clutch

Intelligent no power consumption clutch (being called for short clutch, down together) is the heart of contactor, auxiliary relay, circuit breaker, controller, starter, relay, electromagnetically operated valve, tractive electromagnet, clutch, high-voltage switch gear etc., belongs to electromechanics and electric type.

Present above-mentioned electrical equipment uses electromagnet as clutch.Its shortcoming is to need sticking power consumption, coil heating, adhesive not to exist in real time when exchanging noise, adhesive and desorb big, anti-net voltage fluctuation interference performance difference of electrical equipment interference on every side or the like.In order to address these problems existing many patent applications.For example, to the following patent of Patent Office of the People's Republic of China's application: notification number CN1075819A, CN2105123U, CN2115583U, CN2115584U utilize the contactor of mechanical self-latching sticking shorter because of the mechanical self-latching life-span, and specialized factory does not generally consider to implement; Notification number CN1082243A control circuit for magnetically held electromagnet, CN1086043A mixed type electromagnet, CN1087445A polarized relay, the little power consumption energy saving ac contactor of CN2129466Y, CN2148393Y magneto open-phase protection energy-saving contactor, the little energy consumption contactor of CN2095473U rare earth permanent magnet, CN2103204U magnetic locking contactor etc. mostly are permanent magnetism and electromagnetism hybrid contactor or relay, and its not enough place is that separating rate is still fast inadequately; CN2116270U magnetic energy push-pull device at fixed, its shortcoming are that outer sleeve is a nonmagnetic material, and it is bigger to electronic apparatus interference on every side to drive electromagnetic pulse; The inventor had once applied for following patent to Patent Office of the People's Republic of China: notification number CN2142225Y Contactor without watt consumption, CN2153854Y do not have the power consumption clutch, they all are to lean on the permanent magnetism sticking fully, can not bounce but press down artificially, this also is the common issue with of aforementioned many electromagnet and electromagnetism hybrid contactor, automatic desorb when in addition, the latter two patents end provides under voltage and dead electricity and presses and the circuit of automatic adhesive when sending a telegram in reply.

The purpose of this utility model is to design no sticking power consumption and press deenergize clutch that rebounds automatically and the control circuit of designing this few mechanism of power consumption under release condition, make its automatic desorb when overvoltage, under-voltage and decompression, and the automatic adhesive of when telegram in reply, as the intelligent no power consumption clutch of above-mentioned contactor, auxiliary relay etc.

The utility model purpose is to realize like this.Press Fig. 1, Figure 14, shown in Figure 15, in the magnetic pole corresponding position at the two ends unshakable in one's determination of electromagnet (A) permanent magnets is installed, and be fixed on frame or the bar and become one, as clutch part (B), as action piece, electromagnet (A) is as fixture with (B); Perhaps opposite, (A) be action piece, (B) be fixture.Can provide positive and negative pulse current by such circuit, this circuit is: storage capacitor C1 connects with the coil of electromagnet (A), the commutation of being charged, being discharged by little relay J A.When the little relay J A adhesive of when power supply, dc pulse current by coil (2) to capacitor C 1 until saturated, this moment the permanent magnets on the clutch by the electromagnetism one of electromagnet scold, a force action of inhaling and adhesive, the permanent magnets sticking is on iron core; And overvoltage, dead electricity are pressed or during under voltage, little relay J A desorb, and capacitor C 1 discharge, oppositely electric pulse is by coil (2), clutch desorb.Little relay J A itself possesses decompression desorb function, and the overvoltage desorb need rely on JB adhesive when overvoltage to make JA because of the under-voltage desorb of by-path turn-on, capacitor C 1 discharge, the clutch desorb, the desorb of clutch during phase shortage needs control circuit Figure 17 of pulse, 18 or 19 input termination power A, B are met B, C mutually or A, C phase with another set of same circuit input end mutually again.Connect B, C or A, C phase with the same circuit input end of an other cover again.With in like manner aforementioned, little relay J A ', JB ' can finish decompression, under-voltage, overvoltage makes JA ' desorb, with the power supply of JA ' cut-out JA, desorb in the time of just can realizing the clutch phase shortage.In addition, by shown in Figure 1, the both sides of frame are equipped with active iron ear (10) active iron ear convergence under the pulse electromagnetic field action, and during the no pulse electromagnetic field effect, their meeting opened with certain angle, after pressing down, because the active iron auricular branch is on the step of both sides, and the elastic force of the spring on it (12) surpasses permanent magnets with holding force unshakable in one's determination thereby can bounce.

Clutch can also be by Figure 13, shown in Figure 14, the method of utilizing the permanent magnetism locking to inhale iron, realize that no power consumption is inhaled and treat, promptly go up permanent magnets (5) is installed at the dead bolt frame (17) of (3) unshakable in one's determination two ends, bottom or both sides, front and back, and at center fixation lock shaft or its both sides pin framves (16) of inhaling iron (15).After a direct impulse makes the adhesive of suction iron (15), dead bolt frame (17) just inserts in lock frame (16), and a reverse impulse is because of inhaling the iron adhesive on earth, and lock shaft or lock frame (16) unclamp slightly, dead bolt frame (17) withdraws from the lock frame relaxedly, relies on the spring force desorb and inhale iron (15).

Consequently clutch only needs limited pulse power consumption, and the permanent magnetism sticking does not need power consumption, has only 0.2-1.2 watt of little relay power consumption in the control circuit, does not have the noise of interchange; Because this mechanism one scolds, a force action of inhaling is in moving part, so clutch speed all is quick exponentially; With the electromagnetism sticking relatively, the interference performance of the anti-net voltage fluctuation of this mechanism is fabulous, and is also much smaller to the electromagnetic interference of electronic apparatus on every side simultaneously.Therefore, the electromagnet of above-mentioned contactor, auxiliary relay etc. upgrades with this mechanism, becomes intelligent Contactor without watt consumption with multiple function, auxiliary relay etc., and its performance is very desirable.
