Description

Energy saving ac contactor

The utility model relates to a kind of low voltage control technical field, particularly a kind of push-button switch of using, the energy saving ac contactor of far distance controlled electrical equipment main circuit.

At present, the A.C. contactor of domestic use has CJ ₁₀, CJ ₂₀Deng series, the structure of these series of products is to comprise shell, solenoid, major-minor contact etc., this series of products advantage reliable operation, be convenient to the operation, but its deficiency is an A.C. contactor when work, and the solenoid consumed power is under the situation of power tense, it is very necessary can developing energy-conservation A.C. contactor, and the purpose of this utility model is to provide a kind of energy saving ac contactor that can save energy.

The utility model is realized by following measures: a kind of A.C. contactor that is used for the control apparatus main circuit is at CJ ₁₀, CJ ₂₀Improvement on the series basis, it includes shell, solenoid, button, electromagnet power transmission arm, armature, moving, fixed contact, it is characterized in that it also includes stopping means, electronic switch, their annexations are that an end of power supply is connected with an end of electronic switch with button one end respectively, the other two ends of electronic switch, one respectively with the other end of solenoid, the other end of power supply is connected, its two respectively with the other end of button, one end of solenoid is connected, and the other end of solenoid is connected with the other end of power supply, in slideway (2) and stopper slot (1), can place in the iron core of solenoid central authorities by reciprocating stopping means by magnetic action, stopping means (7) is by armature (5), electromagnet power transmission arm is connected with moving contact, and fixed contact is contained on the shell (6) wherein that electronic switch comprises resistance, electric capacity, diode, triode, voltage-stabiliser tube, their annexations be button an end respectively with R ₁An end, diode D ₁Input link to each other R ₁The other end and voltage-stabiliser tube D _zInput be connected voltage-stabiliser tube D _zOutput respectively with R ₂An end, R ₃An end, BG ₁Base stage be connected diode D ₁Output respectively with R ₃The other end, R ₄An end, C ₁An end, BG ₂Collector electrode be connected BG ₁Collector electrode and R ₄The other end be connected BG ₁Emitter and BG ₂Base stage be connected BG ₂Emitter respectively with the other end, the R of button ₂The other end, an end of solenoid be connected C ₁The other end be connected with often opening of contactor, above-mentioned parts are inserted in the shell.Its operation principle: when pressing the button TA for the first time, the solenoid energising, the armature adhesive of energising back, simultaneously, and limited device locking, the power transmission arm of electromagnet acts on main contact, makes main contact enter closing position, promptly connects main circuit.Its combined floodgate mode is to drive with electromagnetic force, and the spacing method of mechanical force realizes.When release button TA, the solenoid power supply is disconnected, this moment electromagnetic wire coil two ends no-voltage, A.C. contactor is worked under the no-voltage condition.Promptly there is not the operation of pressure.When pressing the button TA for the second time, the solenoid energising produces magnetic force priming armature, drives the limitation locking device and promptly withdraws from lock-out state, and the A.C. contactor main contact is disconnected, and tripping operation separates the state of deactivating.

The utility model compared with prior art has following beneficial effect: it has kept CJ ₁₀, CJ ₂₀The advantage of series has also overcome CJ simultaneously ₁₀, CJ ₂₀The deficiency of series, its effect is: (1) is energy-conservation: can reach 90-99%, this is because of the utility model energy saving ac contactor, and when work, solenoid two ends no-voltage does not promptly have the operation of pressure, and sound-deadening electricity-saving, electronic circuit only need 7～10mA electric current.Prolong contact useful life simultaneously; (2) automatic control detects: when work, and when occurring decompression, under-voltage, the phase failure in the main circuit, output signal automatically, contactless electronic beam switch trips voluntarily, disconnects main line, finishes the protection to main line electrical equipment; (3) long service life, dependable performance: this is because used non-contact type electronic switch; (4) cost is low: this is because solenoid only needs the moment energising, and silicon steel sheet can substitute with general steel commonly used.The cost that has reduced the electronic switch of cost and increase offsets.The cost and the CJ of this energy-conservation A.C. contactor ₁₀, CJ ₂₀Equate.Therefore, alternative CJ _10-20A, CJ _10-40A, CJ _10-60A, CJ _10-100A, CJ _10-150A, CJ _12-400A, CJ _12-600ADeng A.C. contactor, obtain energy-saving effect.
