5: Quasi-state control system:

Automatic preheating system

Output voltage AC220V

Output power 1.5KW/set

Automatic control temperature 50～55℃ (unit temperature)

In the automatic state, the unit is always ready to start automatically when the mains power is lost. It will automatically switch to the network within ≤8S and run at full load. The unit must be in the ready state, pre-heated by the water cooling system, self-circulation, temperature automatic control, to achieve the unit temperature of 50 ~ 55 ℃.

6: Mains automatic detection:

In the automatic state, through the external switch signal, the long-term automatic detection and discrimination of the state of the commercial power. Once the mains is faulty or loses power, it can enter the automatic start state immediately.

7: The unit automatically starts, automatically casts the network, automatically withdraws from the network, and automatically stops the system:

When the unit is in the automatic state, the power failure of the city power is confirmed by the system 3S, and the unit is automatically started (starting three times is a cycle). When rated voltage

At rated speed, it will automatically switch on the grid and supply power. The power supply time of self-starting cast network ≤12S. When the city power returns to normal, confirmed by the system 3S,

The unit automatically trips and exits the network, with a delay of 3 minutes, automatically shut down, and automatically enters the next automatic start-up preparation state.

8: Automatic protection:

With overload, short circuit, high water temperature, low oil pressure, under voltage, oil high temperature, overspeed protection.

With automatic trip and stop function.

It has automatic sound and light alarms for overload, high water temperature, low oil pressure, failure to start automatically, overspeed, high oil temperature, and failure.

9: System description:

The system uses high-reliability electrical products, automatic control, automatic start, automatic shutdown and other automatic control. The industrial computer uses a control computer system to ensure the reliability of operation.

Two: Mains and unit automatic switching system function:

The system has the function of automatically switching the power supply between the mains power supply and the unit power supply, and mainly realizes the automatic switching between the mains power supply and the unit power supply. Under the normal state of mains power, the system has the function of giving priority to mains power supply. When mains power is lost, the system can automatically switch to the unit side, and the unit automatically supplies power to the load; when the mains power returns to normal, the system can automatically switch to the city On the power side, the mains power is automatically supplied to the load, and it has the function of priority power supply.

According to the different numbers of generator sets and mains, it can be divided into: single unit and single mains switching, single unit and double mains switching, double unit and single mains switching, double unit and double mains switching. Their functions are as follows:

1: Switch between single unit and single mains:

Parameter display function: mains voltage, generator voltage, load current.

Status display function: city power normal/fault, generator operation/fault, city power/generator load.

Manual control function: manual/automatic/maintenance, generator/mains load.

Automatic control function: city power failure, delay confirmation (time adjustable), issue starter unit command, generator starts to load after unit starts running normally;

Mains recovery, delay confirmation (time adjustable), mains on-load, the unit automatically shuts down after 3 minutes of no-load operation (adjustable).

2: Switch between single unit and dual mains:

Parameter display function: 1st mains voltage, 2nd mains voltage, generator voltage, load current.

Status display function: No. 1 mains normal/fault, No. 2 mains normal/fault, generator operation/fault, No. 1 mains/second mains/generator

Load.

Manual control function: manual/automatic/maintenance, main/standby mains selection, generator/one-way mains/two-way mains load.

Automatic control function: main city power failure, delay confirmation (time adjustable), standby city

Electricity on-load: When both mains powers fail, a command to start the unit is issued. After the unit starts and runs normally, the generator is loaded; the mains power is restored

Reset, delay confirmation (time adjustable), the mains load, the unit automatically shuts down after 3 minutes of no-load operation (adjustable).

3: Switching between dual units and single mains:

Parameter display function: mains voltage, No. 1 generator voltage, No. 2 generator voltage, load current.
