Primarily used to monitor power supply circuit, when the common power supply failure, the automatic switch to standby power, thus completing the conversion of power system.
This product is particularly suitable for use in power does not allow to cut that the power supply of the important places, To meet the needs of the site. The Automatic Transfer could be choose from the vote since the complex, since the vote of no-self-recovery, Power to the Power Grid, power grids on the generators, a wide range of functional work. The product applies to rated voltage AC400V and below, frequency 50Hz, rated current of 10A to 800A power supply system.
Structure and characteristics
ZBQ3 series smart double-power automatic transfer switch Includs a two three-pole or four pole molded case circuit breaker and its accessories (auxiliary, alarm contacts), Mechanical interlock transmission mechanism, Intelligent Controller and so on. Divide two types integral and split structures. Integral structures is the controller and the executing agencies mount on same base. Split structures is a controller installs in the enclosure panel, Executing agency installs in the base in the enclosure by user. Controller and Executing agency is connected with a 2m long cable.
Characterized:
Between the two circuit breakers has has reliable mechanical interlock and electrical interlock and protection devices, The complete elimination of the two circuit breakers probably be cutted at the same time.
Intelligent controller Control core uses SCM, It's hardware simplicity, powerful function, Extended to facilitate, high Reliability.
Its function include Short circuit/overload protection, Overvoltage/undervoltage/phase failure automatically switch and Intelligent alarm.
Automatic switching parameters can be set in the external free
With the operation of motor Intelligent protection.
This product has fire control circuit, when fire control center give a order to Intelligent controller, two circuit breakers gate into Sub-Gate state.
Left computer network interface to prepare to achieve remote control, remote adjustment, remote, telemetry and other functions.
