10kV dual power automatic switching device

1. An overview of the

With the development of the society, people has higher requirement on the power supply reliability.Many occasions to ensure the reliability of power supply with two way power supply, which requires a product in reliable switching between two power supplies, the company produced ZYKCQ - 50 double power automatic switching device is designed in order to meet the demand of this kind of development.

ZYKCQ - 50 double power automatic switching device consists of two high voltage vacuum circuit breaker and intelligent controller of two parts.Applied to the communication12 kv 50 hz, rated voltage, rated current 1250 a dual power supply system, when the power failure or undervoltage occurred in power source automatic switch all the way to the other along the normal power supply, reliable guarantee for the continuity of power supply.At the same time many advantages such as short circuit and over current protection interlock function, effectively avoid the unnecessary power supply shock again when load failure.In common power failure occurs, switching device can complete with standby power automatic switch, to ensure the reliability and security.Also can according to the needs of the load for the switching between the two power supplies.Particularly applicable to not allow the important place of power, as an important electrical control device to ensure continuous power supply, is with high voltage vacuum circuit breaker of the replica dual power automatic switch device.As a new generation of novel design, perfect in performance, safe and reliable, high degree of automation, wide using range of dual power automatic switch products.

Products are widely used inOil fields, mines, 10 kv distribution line, industrial and mining enterprises, 10 kv line.

7. Debugging and installation

7.1 debugging

* Before installation please click the following method for debugging, commissioning normal rear can put into use.

7.1.1 Lord for electric automatic conversion debugging

8.1.1. 1 press the logo, on the controller to form a complete set of two cables and high voltage vacuum circuit breaker tighten-up, corresponding to the air outlet.

8.1.12 to the master, for power supply.

8.1.1. 3 open two power switch of the controller, the product into the working state.The main electric power supply, if the primary electrical high voltage vacuum circuit breaker is in a state of breaking past the main electrical delay closing time main power switch.If no action may be blocking, please manually press the main power switch button to manually switch is unlocked.Shut down the main electricity, main electric controller should lose the main electric brake high voltage vacuum circuit breaker points.After a delay closing time for electricity for electric high voltage vacuum circuit breaker closing, for electrical work.Master to complete an automatic conversion process ().Give the main electric power, master electricity to make controller should be detected electric high voltage vacuum circuit breaker breaking, the main electrical high voltage vacuum circuit breaker through the main electrical switching delay closing time, the main electrical work.Complete an automatic conversion process (to master).

7.1.2 Over-current protection

This product factory set data flow for current transformer secondary side 5 a, quick break for 15 a secondary side, according to the user's need to make changes.Through raising the inverter for high voltage vacuum circuit breaker with large current, make the secondary side current is greater than 5 a, conversion device will be closing due to over current atresia handle breaking current switching work vacuum switch, two power supplies are not automatic switching.Unlock method for manual press the corresponding closing unlock button on the panel, or by remote control to master, and the corresponding electric remote control switch to unlock.

7.1.3 Remote debugging.
