A, double power automatic switch product overview
Q ( DZ47 ) type automatic power switch used in AC 50HZ, rated voltage 380V
And the following double power supply system, with automatic or manual to make way to accomplish common power switching between.
The switch is mainly used in hospital, shop, bank, chemical industry, metallurgy, building up layers, such as military facilities
The power does not allow important occasions.
Two, the basic structure
Q ( DZ47 ) automatic power supply switch is mainly composed of a power supply switch execution circuit breaker (including the common power supply
Implementation of circuit breaker QN and alternate execution circuit breaker QR each one), automatic control box, electric operation mechanism
Part. Circuit breaker QN and QR are maintained the original over-current and short circuit protection function, can be done at
To pass, fault and protection of the main electrical appliances with.
In three, the assembly and the connection
When wiring, power N served as commonly used power execution circuit breaker QN, R served as standby standby power supply
Implementation of QR power circuit breaker. When QN and QR four circuit breaker connection mode, according to the wiring diagram, the (negative )
QN and QR, 1, 3, 5 for three-phase incoming line terminal, 2, 4, 6 for terminal 7, zero line end, 8 is the zero line
Outlet end. If the selection of circuit breakers for the three circuit breaker, it must be common power ( N ) of the zero line NN and reserve
Power ( R ) of the zero line NR also received a three special wiring of zero terminal.
Dual power switch automatic controller working power supply from the circuit breaker QN and QR wire inlet end and a zero line
If the selection of circuit breakers for the three circuit breakers, have to take two to zero line NN and NR, the three special wiring
Zero terminal in two sets of circuit breakers intermediate. The automatic power supply switch installation, wiring process, do not have the original.
Connected to the incoming line terminal of the control line to get rid of, broken and short circuit.
