Off-phase and three-phase motor-phase protection circuit


To this end, when a motor-off phase or-phase run-time. Immediately turn off the motor control circuit to make it from the power grid. Three-phase motor phase failure, phase fault protection circuit mainly by the three-phase synchronous detection circuit, phase failure and phase sequence logic circuit and output circuit to identify the composition of the protection logic block diagram shown in Figure 1 and the phase-phase fault protection output AC relay normally closed contact in series with the motor control circuit, when a failure occurs, the Park should be the output relay, normally closed contacts disconnect the motor control circuit and cut off the light corresponding alarm signal. Net. . L_I 1 phase-phase protection and unfortunately the protection circuit block diagram of the electrical box 2 principle surplus cPSRLHflLL, QQ × LHLHHXHH a 23 a plant protection 1 book 2 is an electrical schematic circuit synchronized output transformer T ~ T to provide off inspection phase and wrong and Yan 6 circuit protection, the protection works as follows; one-phase protection circuit of the circuit of each phase were prepared from the separate detector, simultaneous output of the transformer equipment believed by the number of transistors consisting of inverted V ~ v device and the diode v ~ V. Composition or gate to the output circuit, when the normal three-phase electric Yu, transistor VrV turn, anti-titanite output low,p90x workout schedule, set up by the door two tube v ~ V. As the output M point is low, transistor V cut-out relay Kv no action. When the phase of any one phase (such as A tree) occurred off phase, the transistor V cut-off, its collector potential is high, the diode conduction v, M point is high, the delay power-off C. Delay after the transistor turn-on V, the output relay Kv pull, cut off its normally closed contacts disconnect the motor control circuit, closing its normally open contacts, electric light-off phase alarm signal LED (RD). The role of resistance R can reduce the transistor V, IceO, while the delay capacitor C. Increase in the discharge circuit protection circuit set off the tallow is part of the delay in order to prevent the electrical motor starting or running that may arise during the short three-phase imbalance and malfunctions phenomenon. II. Phase-phase fault protection circuit to protect the integrated flip-flop D. , D, and non-¨ b Road D, Dz phase sequence consisting of sub-brake logic control circuit. D. , D. Dual D flip-flop [model 40L3),tory burch outlet, pulse rising edge,tory burch outlet, the truth table Annex attack. A synchronous three-phase synchronous signal output transformer next transistor V:. ~ V provided to the phase sequence logic control circuit, when ABc phase of the phase sequence is correct, the relevant point of bamboo waveform shown in Figure 3, can be seen from Figure 3, D. Trigger the Q-side and D flip-flops are a hundred knock-level business, this time with the non-gate D output is low, transistor V off, the output relay Kv: Hu is not wrong when the action occurs, such as B-phase and c relative to brag, then the relevant point Yun waveform shown in Figure 4, H24 - l Division 1-step voltage [] [{r - 1r a -1 [b - '] one hundred twenty-two two:' i ' Figure 3 Aiba is the relevant point of moisture in Bogotá j can be seen on the map, D flip-flop of Q Jing and D. Trigger the Q-side are LOW, the NAND gate D: output high, transistor 1Ve conduction, the output relay KV suction units, cut off its normally closed contacts disconnect the motor control circuit fault with the alarm light leek signal LED (GN). Can also be analyzed, when the A phase and B phase or A disgrace for phase c phase when, D, flip-flop Q terminal and the D. Trigger the Q-side are low-power peace,mac cosmetics wholesale, love and a E the same as the above analysis. This phase-and-phase protection circuit of the elevator in my company has been using. ', R I -] wide -],] mouth 4 when the prince Yu-phase (B phase and C phase exchange) the relevant point waveform
