Double power supply automatic switch product overview:
RZMQ1 (DZ47) type automatic power supply switch is used in AC 50HZ, rated voltage 380V
And the double power supply system, automatic or manual way to complete switch made common power supply.
The switch is mainly used in hospital, shop, bank, chemical industry, metallurgy, building up layer, military facilities
Important occasions, do not allow electricity.
• basic structure
RZMQ1 (DZ47) automatic power supply switch is mainly composed of a power conversion circuit breakers (including the common power supply
Implementation of RN circuit breaker and alternate executive circuit breaker QR each one), automatic control box, electric operation mechanism
Parts. Circuit breaker RN and QR were maintained over current protection and short circuit protection function of the original, at the same time as the
To pass, fault and the main electrical appliances with protection.
• assembly line
When wiring, power N shall be such as the commonly used power execution circuit breaker QN, R should be as standby standby power supply
Power circuit breaker QR. When QN and QR four circuit breaker, connection mode according to the wiring diagram (negative), the
QN and QR, 1, 3,5 for the three-phase input, 2,4,6 as phase terminals, 7 as the zero line into the line side, 8 as the zero line
The outlet end. If the selection of circuit breaker is three level of circuit breaker, it must be a common power supply (N) of the zero line NN and the standby
Power supply (R) of the zero line NR also received three dedicated wiring of zero.
Line from the circuit breaker QN and QR dual power switch power supply automatic controller end and the zero line
If the selection of circuit breaker for three circuit breakers, must connect two to zero line NN and NR, the three level special wiring
Zero terminal in the middle two circuit breaker. Installed in the automatic power supply switch, wiring process, must not be the original.
After the machine control line into the line in the end off, break and short circuit.
