Abstract

The utility model relates to an electric distribution cabinet for three-phase and single-phase circuit power source distribution, which comprises a box body, an upper door, and a lower door. Two indicating lamps, an ammeter, a voltmeter, and a switcher are arranged on the upper door; an electric meter, a wiring terminal, an intermediate relay and a fuse are arranged on a device plate of the upper part in the box body; the middle part in the box body is provided with a large capacity automatic air switch, and the lower part is provided with a current mutual inductor, a three-phase small capacity automatic switch, and two single-phase small capacity automatic switch in turn; the bottom part in the box body is provided with a row of neutral bar, and the top is provided with earth wire. The electric distribution cabinet can satisfy the need of the existing non-standard microwave room of moveable communication station with bar-shaped machine frame.

Description

The power distribution cabinet that three-phase loop and single-phase ring current distribute

The utility model belongs to the power distribution cabinet of a kind of three-phase loop and the distribution of single-phase ring current, and the mobile communication equipment station microwave machine room that its adapts to non-standard bar shaped frame uses.

The primary structure of existing power distribution cabinet is case, plank frame, and its major function is switching and power distribution, can not satisfy the needs of the mobile communication equipment station microwave machine room use of existing non-standard bar shaped frame.

The purpose of this utility model provides the other three-phase loop of needs and the power distribution cabinet that single-phase ring current distributes of using of mobile communication equipment station microwave machine that a kind of energy satisfies existing non-standard bar shaped frame.

The utility model comprises casing, door, device board, it is characterized in that: it has calls 1,220v indicator light 31 is being equipped with to the doorstep in Xiamen 2,24V indicator light 4, ammeter 5, voltmeter 6, change over switch 7, kilowatt-hour meter 8, binding post 9, auxiliary relay 10 and fuse 11 are housed on the device board of casing internal upper part, in casing, on the device board at middle part big capacity automatic air-break switch 12 is housed, current transformer 13 is housed successively on the device board below this automatic air-break switch 12, three-phase low capacity automatic switch 14 its capacity are 50 or 40 amperes; Single-phase low capacity automatic switch 15 its capacity are the 20-25 ampere; Single-phase low capacity automatic switch 16 its capacity are 16 amperes, to satisfy the needs of the various distinct devices of user, at the casing inner bottom part zero bus row 17 are housed, and at the casing inner top ground wire 18 are housed.

Major advantage of the present utility model is that it can satisfy the needs of the mobile communication equipment station microwave machine room user's who has non-standard bar shaped frame now various distinct devices uses.

Description of drawings:

Fig. 1 is the power distribution cabinet schematic appearance of this power distribution;

Fig. 2 is the power distribution cabinet internal structure schematic diagram of this power distribution;

Fig. 3 is a big capacity automatic air-break switch 12 among Fig. 2, current transformer 13, three-phase low capacity automatic switch 14, the wiring schematic diagram of single-phase low capacity automatic switch 15 and single-phase low capacity automatic switch 16.

Action performance below in conjunction with the power distribution cabinet of this power distribution of description of drawings:

When big capacity automatic air-break switch 12 was in combined floodgate, the end of incoming cables, top of three-phase and single-phase low capacity automatic switch 14,15,16 was charged, and the leading-out terminal of bottom is not charged;

When external power source had electricity, voltmeter 6 had indication, and indicator light 3 has indication (bright), manual change-over switch 7, and detecting three-phase voltage has indication on voltmeter 6;

When three-phase low capacity automatic switch 14, when single-phase low capacity automatic switch 15,16 was connected load, kilowatt-hour meter 8 had indication;

When external power source did not have electricity, indicator light 4 had indication.
