Description
Technical field
The utility model belongs to magnet stopper.
Background technology
Magnet stopper is to utilize galvanomagnetic effect to realize the device of braking, is the visual plant that the elevator operation is controlled automatically.
Both-end is two pushes away magnet stopper, and two ends are identical.Existing conservation measures is to adopt the two ends resistance to be respectively the R coils from parallel connection of coils to start the method that series connection maintains and realize energy-conservation, as Fig. 1 a or Fig. 1 b, by two end-coil L1, L2 relay K turn-on time T, coil L1A relay termination one contact, coil L1B relay termination four contacts; Coil L2C relay termination three contacts, coil L2D succeeds electrical equipment two contacts, and San, contact, contact four is moving contact.Time relay KT energising, as Fig. 1 a, San, contact, contact one is connected, and Si, contact, contact two is connected, and two coils from parallel connection of coils start, and starting power is PQ; Time relay KT outage after time delay, as San, contact, Fig. 1 b contact five is connected, Si, contact, contact six is connected, and two end-coil series connection maintain, and holding power is PW.
Armature contacts with end cap owing to maintaining, without magnetic resistance, still excessive through theoretical research and practice proof maintenance energy, if make holding power be less than PW, can just maintain safely, has so not only saved the energy but also can reduce temperature rise, strengthens suction.But, because the resistance of two coils is identical, the resistance value ratio of series and parallel connections is 4, causing starting power PQ is four times of holding power PW, can't reduce holding power again, causes wasting energy.
Summary of the invention
The utility model provides a kind of energy-saving electromagnetic brake, high to solve holding power, causes the problem wasted energy.
The technical scheme that the utility model is taked is: an end-coil comprises main winding one, auxiliary winding one, other end coil comprises main winding two, auxiliary winding two, the resistance of each winding is identical respectively, the A1 end of main winding one is connected with the contact one of time relay KT, the B1 end is connected with the contact seven of time relay KT, the C1 end of auxiliary winding one is connected with the contact six of time relay KT, the D1 end is connected with the contact eight of time relay KT, the A2 end of main winding two is connected with the contact nine of time relay KT, the B2 end is connected with the contact ten of time relay KT, the C2 end of auxiliary winding two is connected with the contact 15 of time relay KT, the D1 end is connected with the contact five of time relay KT, wherein contact six, contact seven, contact eight, contact nine, contact ten is moving contact, contact 11 is connected with contact 12, contact 13 is connected with contact 14, Yi He contact, contact four connects positive source, Er He contact, contact five connects power cathode, contact three skies connect.
The utility model has the advantages that novel structure, when the startup in parallel of coil main winding, resistance is constant, when the coil series connection maintains, each main winding is with after auxiliary winding is connected, increased the coil resistance, made the resistance value ratio of series and parallel connections be greater than 4, thereby made holding power lower than its former holding power, can save the energy, reduce temperature rise, in the constant situation of maintenance starting power PQ, descending to hanging down maintains power P W, can meet the safe operation requirement, optimize product design, improved the quality of product.
