四. normal working condition:
1: Air Temperature：
(1)、Maximum temperature +40℃; Average temperature within 24Hrs should not be
beyond +40℃
(2)、Minimum temperature-5℃；
(3)、Average temperature within 24 Hrs should not be beyond +35℃
Notes：
The customer should consult the manufacturer when the top limit of air temperature
is over +40℃ and the lower limit of the air temperature is below -10℃ or -25℃.
2. Ambient temperature:
-5⊥ - +40⊥; the average value within 24h shall not exceed +35⊥. Relative humidity at +40
⊥ shall not exceed 50%. Higher humidity is permissible at lower temperature condition.
When the highest monthly average relative humidity is 90% in the humiddest month,
the lowest monthly average temperature of this month is +25⊥. And the influence of dew on product
surface due to
temperature changes should be taken into consideration.
3. Altitude of installation place shall not exceed 2000m.
4. Pollution grade: grade iii.
5. Installation instruction: vertically installations and the vertical angle shouldn’t
exceed 22.5.
五、features:
1. Excitation Control System; DC Pulse Operation; fast switching; lack of coil heating;
noiseless; conserving energy.
2. Manual manipulation and power operator are both available.
3. Reliable interlock makes sure that the host and the backup power cannot be electrified
at the same time.
4. The adoption of large contact with superior performance makes conductive part steady
and reliable.
5. Strong Arcing ability is subject load.
6. In accord with the isolator of the qualified rate.
六、operating principle
When the side voltage relay of main power changes, the side voltage relay of standby
power works and switch on its
time relay, then turns on the middle relay to supply power for its rectifier bridge after
a certain of delay, and drives control loop electrical wires, thus the switch acts, the loop
of main power is disconnected. When the main power turns to normal, its voltage relay
works turns on the middle relay to supply power for its rectifier bridge after a certain of
delay, and drives control loop electrical wires, thus the switch acts, then the standby
power is cut and the main power supply restores.
七、construction of switch
This series of HZQ5-40/630 automatic transfer switches are consisted of auxiliary contact and main contact
combined through the mechanical drive. Under the exact and rational design, the
electrical equipment and the machine link together at the same time to make sure that
the main power and the standby power won’t be turned on simultaneously. The main
contact is made of Silver-tungsten Alloy and Silver-Tungsten Carbide which have strong arc-resistance, so their lifetime can be prolonged. What’s more, arcing ability is strong
and it can be transferred live and can be also transferred by hand through operating
handle 2. It adopts electromagnetic driving and DC Pulse system so that it can play an
important role in reducing the ageing of coins and saving electric energy. The electrical
clearance and creepage distance meets the standards with the function of insulation.
A1,A2 and B1,B2 are two groups of control power’s connection ports, and A3,B3 are
indicative terminals of two power sources’ close-break and provide users with two groups of auxiliary contacts(A4,A5,B4,B5) for other utilities.
