Customized precision distribution box with high-precision sheet metal

System composition:

1, the business space intelligent power distribution cabinet includes two parts: hardware system and monitoring system.

2, the hardware of the system mainly includes the dual power supply switching, city power distribution, UPS circuit of power supply, bypass maintenance system, output branch distribution, lightning protection system and so on.

3, monitoring system by the monitoring module and the software composition, a full range of monitoring and recording of power, in various parts of the current detection, voltage, current threshold alarm in advance and action alarm switch.

4, the monitoring system also includes the fan detection, transformer temperature management, sound and light alarm and other functions.

Hardware component:

1, electric dual input automatic switch - ATS (optional)

When the control system detects a power failure, it automatically switches to the other input power supply. Dual input power supply redundancy, which increases the reliability of power system.

2, EPO/REPO function (optional)

The EPO/REPO function is connected with an emergency power switch. The input and output power of the device is cut off when the emergency switch is off, and the output power of the device is cut off.

3, isolation transformer (optional)

Input isolation transformer is optional configuration. The output power of the transformer is the same as the maximum load rating of the power distribution cabinet, which can be effectively isolated from the input power supply.

4, the UPS input / output and manual bypass switch (optional)

Intelligent power distribution cabinet integrated UPS input and output and maintenance bypass switch, in the case of the use of three circuit breakers, can make the UPS and the public power isolation. According to the capacity of the UPS, the configuration of different specifications of the switch.

5, the output of the UPS shunt (optional common switch)

We can use the conventional shunt output rail type miniature circuit breaker or miniature circuit breaker hot plug. 21 way for a group, you can reach 21 ~ 84 circuit. If the hot swap a cassette switch tool free flexible heat change, online expansion and according to the site configuration and change of load adjustment three-phase equilibrium.

6, the city electricity output branch (optional)

Can provide uninterrupted power supply at the same time, to provide electricity for air conditioning, shunt, lighting, electric load. Electricity output shunt can also use hot pluggable switch card.

7, lightning protection module

The standard configuration of the C class lightning protection module is provided by Shang Yu precision distribution. If required, it can provide the B class lightning protection module, to provide B lightning protection.

Monitoring function:

1, the local management function: the wide screen of the touch screen, Windows human interface, with password protection function, can show the power state of the bus and the loop.

2, remote management function; the distribution system is fully incorporated into the computer room monitoring system; provide RS232 / 485 or LAN a variety of intelligent interface communication, rich content detection; all loop current control, switch state, running load rate, room distribution system operation status at a glance, but also easy for users to early discover the hidden safety trouble, as soon as possible to evade risks.

3, sound and light alarm function, which prompts the user fault or abnormal state, including: the main road high and low pressure, the main road overload alarm, the input voltage, the current flow, voltage imbalance, transformer over temperature, etc..

4, the history of the operation and fault record store, can record every time the operation of the switch, to help identify the cause of failure, easy to fault analysis, distinguish responsibility.

5, load curve record, can record the change of the load of a day, determine whether the UPS, the battery is equipped with the right, as well as the system in part of the failure of the redundancy.

6, auxiliary alarm contact, to provide users with remote alarm, it is controlled by the alarm signal. As long as the detection of any alarm, integrated alarm contact on the action.

7, bus monitoring parameters include: three-phase input voltage, current, frequency, power, active power, power factor, harmonic percentage, load percentage, electricity (can be according to customer needs monthly measurement etc.

8, branch monitored parameters (optional) including: percentage of branch rated current and actual current and branch load and branch switch state, branch power (monthly / quarterly consumption)

9, other monitoring (optional): transformer temperature monitoring
