四、performances and features
1. Adopting double rows compound contact, traversing structure, micro -motor for energy storage, micro-electronics control technology and almost reaching
non-electric arc.
2. Adopting reliable mechanical interlock, electric interlock, and independent load
switch operating safely.
3. Adopting electric nulling-technique, and forced reset to zero in case of an emergency (by disengaging two
powers) to meet the need of fire fighting blocking.
4. Implementation load isolating switch adopts single motor driver, and it can switch
safely, steadily and quietly with small impact force.
5. Only in the instant switch-over time of implementation load isolating switch, the manipulator drives the electric
motor and the electricity passes. But the operating current is not necessary in steady
state, and the energy saving result was apparent.
5 Implementation load isolating switch has the interlock of mechanism to assure that
the main power and the standby power work properly with non-interference.
6 Having the factions of padlock and obvious indication of on and off, so make the
isolation between the power source and the load come true
7. Having high degree of automation and good safety feature and service life achieve
more than 8,000 times.
8 Mechanic-electrical unification design and the switch adopting the international advanced
technology of logic control transfers exactly, agile, smoothly with strong anti-jamming ability and without external interference.
9 When the main power switches on, the standby power switches off and vice
versa. Both of the main power and standby power can be off at the same time.
10 Convenient installation and control loop is connected plug-in terminals.
11. Having four operating functions: urgent manual operation, electric remote
control operation, urgent disconnection operation under the condition of automatic
control, automatic control operation.
五、Scope of applications
HZQ51000-1000, 3200 series of switches are
六、Environment of Usage
1. Altitude shall not exceed 2000m.
2. Ambient temperature shall not exceed 40℃ or fall below -5℃ and relatively temperature shall not exceed 95%.
3. Exclusive from the ambient medium of explosion
4. Exclusive from the environment of snow and rain.
Notes: if it is expected to work in the temperature of being >500℃ or <-5℃ to -45℃, customers should explain it to the manufacturer.
