Abstract
The utility model relates to a double pressure controllable rectifier which is simultaneously provided with a high voltage delay trigger and a low voltage delay trigger to trigger controllable silicon. Alternating current voltage produce direct current voltage at both ends of an electromagnetic brake coil, direct current high pressure can realize high power starting attraction, and direct current low voltage can realize the function of maintaining attraction with low power. Because the coil has low voltage, small current, a small heating amount and a large attracting clearance when maintaining attraction, the coil has good insulating performance, the resistance variation of the coil is small, and the magnet yoke of the coil has small influence to the attracting force of armature iron when a brake works repeatedly. The utility model can directly achieve the purpose of quick brake because the coil has the low voltage and small electromagnetic energy when maintaining the attraction.
Description
The utility model relates to a kind of device that can carry out rectification to AC supply voltage.
Two pressure controlled rectifiers are used for electromagnetic brake, the rectifier that in the past was used on the electromagnetic brake has three kinds, be half-wave rectifier, full-wave rectifier, all-wave controlled rectifier, these three kinds of rectifiers are the triggerless devices for preceding two kinds, and the third is triggered by high direct voltage.So the coil of electromagnetic brake seriously generates heat after using the short time, cause the decreasing insulating of coil, it is big that the resistance of coil becomes, the coil yoke of electromagnetic brake is descended to the suction between the armature, working clearance between electromagnetic brake coil yoke and the armature easily increases after working repeatedly, therefore for guaranteeing the adhesive performance of brake, the user must often adjust the working clearance between coil yoke and the armature, operates very inconvenient; When original electromagnetic brake uses will with the A.C. contactor logotype, could realize fast braking.Promptly be when outage, with the electromagnetic energy rapid release on the brake coil, make coil yoke rapid release armature by A.C. contactor, can realize fast braking, this has just limited the scope of application of electromagnetic brake.
The purpose of this utility model is to provide a kind of high pressure time-delay trigger and low pressure time-delay trigger of being equipped with simultaneously to trigger the two pressure controlled rectifiers of silicon controlled, make alternating voltage produce high direct voltage and dc low-voltage at electromagnetic brake coil two ends, to realize high-power adhesive, small-power is kept the function of adhesive.And the coil voltage of keeping adhesive is low, electric current is little, caloric value is little, and it is big to start the adhesive gap, the good insulation preformance of coil, and the resistance variations of coil is very little, and the coil yoke was influenced little to the suction of armature when brake started repeatedly.Because the voltage when keeping adhesive on the coil is low, electromagnetic energy is little, can directly realize fast braking.
The utility model is to implement like this
Two pressure controlled rectifiers are by piezo-resistance RV, controllable silicon VT, fly-wheel diode VD
