Example:

The machine room integrated power distribution cabinet of the present invention adopts a modular structure and is composed of three parts: a power distribution function module, a single-phase mains dual power supply (STS) automatic switching module, and a UPS power supply module, as shown in FIG. 1 .

The power distribution module is composed of three-phase mains input (including three-level surge protection of three-phase power supply), output distribution, single-phase mains dual power input and output power distribution unit, UPS power output distribution, zero discharge , ground row unit and other four units;

The mains (single-phase) dual power supply (STS) automatic switching module is composed of 1 Osip RSTS-1163A-B (63A/220V) rack-mounted (STS) dual power switcher;

The UPS power module is composed of 1 Rittal PMC 12UPS DK 10KVA UPS host, 4 sets of PMC 12DK 10K battery packs and 1 set of 3 units such as multi-channel power failure, incoming call, and phase loss automatic alarm;

The modules installed from top to bottom in the cabinet are: (1) self-made multi-channel power failure, incoming call, and phase-loss automatic alarm; (2) Rittal PMC 12UPS DK 10KVA rack-mounted UPS; (3) Osip RSTS- 1163A-B (63A/220V) rack-mounted (STS) dual power switcher; (4) self-made rack-mounted mains dual-power switching power distribution and UPS output power distribution module; (5) rack-mounted power distribution module 4 sets of Rittal PMC 12DK 10K battery packs are installed on the back. All the power distribution equipment in the entire computer room is integrated in one cabinet, which has a compact structure, optimizes the equipment layout of the computer room, and improves the automation of power management in the computer room.

The system configuration of each unit of the mains power distribution function module is:

(1) Three-phase mains input and output power distribution unit: the mains three-phase power introduced from the 15th floor (north) strong electric shaft is distributed to the air conditioner in the computer room, the large dispatching monitoring screen in the hall, the operating console in the hall and the cabinet in the computer room The mains power supply PDU, and provide surge protection for the three-phase mains. Hangzhou Hongertai HY380P-20 surge protector is used for lightning protection of the third-level power supply of the mains; see 2.

(2) Single-phase mains dual power supply input and output power distribution unit: distribute 2-way single-phase power supply from the 15th floor (north) strong electric shaft dispatching busbar and lighting busbar to OSIP RSTS-1163A-B dual power supply The first input power and the second input power of the automatic switcher are controlled by the STS dual power switcher and distributed to the Rittal PMC 12DK 10KVA UPS host;

UPS output power distribution unit:

After the power output by Rittal PMC 12DK 10KVA UPS is distributed by the UPS output power distribution function module, it mainly completes the power supply for important equipment in the computer room. Mainly include: (1) UPS power supply for network communication cabinets, workstations/PC cabinets, SUN workstations/server cabinets, dispatching and monitoring large-screen control cabinets; (2) UPS power supply for operating consoles in the hall; (3) Monitoring in the computer room , access control, emergency lighting UPS power supply; (4) UPS power supply for the director's office; (5) UPS uninterruptible power supply for the building access control system. The detailed configuration is as follows (see 3-8 for details):

Zero row, ground row unit:

The zero row of mains power and UPS power supply in the integrated power distribution cabinet is set independently, and the ground row is shared.

Mains (single-phase) dual power supply (STS) automatic seamless switching module:

The 2-way commercial power introduced by the dispatching busbar and the lighting busbar is connected to the Osip RSTS-1163A-B dual power automatic switcher in the integrated cabinet after power distribution and distribution, and the power supply of the dispatching busbar is connected to the Osip RSTS The power of the first power input lighting busbar is connected to the second power input of the STS; when the two power supplies are normal, because the first power input of the STS is the main and standby power, the STS automatically connects to the first input power. When the dispatching busbar is unexpectedly powered off or overhauled, the STS will automatically switch to the hot standby power supply terminal within ≤6ms, which is connected to the second power input terminal of the lighting busbar. If the lighting busbar is unexpectedly powered off or overhauled, the STS will not act, and the state of being powered by the first power input will remain unchanged. The switching time of Osip RSTS-1163A 63A/220V STS dual power automatic switcher is ≤6ms. Because of switches, computers, servers, UPS and other electronic equipment, when the power switching time is less than 8 ms, there will be no downtime and the operation will remain normal. Therefore, the continuity and reliability of power supply are ensured. Realized the seamless automatic switching of mains dual power supply.

When installing the STS dual power automatic switcher (redundant switch), in order to ensure that the STS can realize the seamless switching of dual power sources, it is necessary to ensure that the first power input and the second power input of the STS maintain the same frequency and phase. Therefore, when the first power input of the STS is connected to the A phase of the dispatching busbar, the second power input of the STS must be connected to the A phase of the lighting busbar, so as to keep the two mains at the same frequency and phase, and make the switching time of the STS ≤6ms.

UPS power module, which mainly includes UPS host selection:

In order to realize the seamless automatic switching of UPS/mains dual power supply, the configured UPS must be a pure line UPS instead of an online interactive UPS. This is mainly because when the pure online UPS is in the mains power failure or power recovery, the switching between the mains mode and the battery mode of the UPS has no conversion time at all, that is, "0" switching, which effectively guarantees the load when the power is switched. continuous and reliable operation. While the online interactive UPS has a switching time of 4-10ms between the mains mode and the battery mode when the mains power fails or is restored, it cannot guarantee the uninterrupted operation of the load. In the case of mains power failure, it is even more impossible to realize seamless automatic switching of UPS/mains dual power supply. Rittal PMC12UPSDK 10KVA UPS with advanced IGBT rectification technology is selected for this case.

Battery installation:

The UPS battery uses 4 Rittal 10K UPS battery expansion packs in parallel to supply power to the UPS host. The physical size of the battery expansion pack is (height) 132mmX (width) 440mmX (depth) 660mm. According to the design needs, it is integrated in the mains/UPS dual power supply switch (power distribution). To make full use of the limited space in the cabinet, install the battery expansion pack behind the customized rack-mounted power distribution cabinet, as shown in Figure 3-4. For this reason, it is necessary to put forward special configuration requirements when ordering Rittal cabinets:

(1) Add 4 new (width) 440mm*(depth) 660mm laminates for installing battery expansion packs, and the laminates can bear more than 60Kg;

(2) Add an installation column on both sides of the cabinet, and install it at the 440mm position of the cabinet (from front to back) to install the extended cladding board of the battery.

(3) Add 3 pieces of "L" type 660mm long installation guide rails for installing UPS mainframe and Osip RSTS-1163A integrated distribution cabinet Measuring instrument chooses Shanghai Sophy digital display three-phase voltage/ammeter 1, single-phase 2 volt/ammeters, respectively measure the voltage and current of the three-phase mains, the voltage/current of the STS input power supply (1), and the voltage/current of the STS input power supply (2). It is equipped with yellow, green and red power indicator lights; all circuit breakers are Schneider products.
