Abstract
The invention discloses an uninterrupted power supply circuit, which comprises air-break switches, disconnectors and a high-voltage duplicate supply. The high-voltage duplicate supply is connected with two power supply circuits, one air-break switch and one disconnector are arranged on each power supply circuit, an output line of the high-voltage duplicate supply is connected with the transformer, an external connection circuit is arranged on a low-voltage side of the transformer, and a standby line of a low-voltage duplicate supply is arranged on the external connection circuit. By the adoption of the uninterrupted power supply circuit, resources and investment expenses of an engineering project are saved under the circumstance of guaranteeing a normal and uninterrupted power supply.
Description
Technical field
The present invention relates to technical field, specifically belong to a kind of uninterrupted power supply circuit.
Background technology
It is high-rise mostly existing residential quarters are, its power supply is divided into two parts: a part is residential electric power, and by management title office of power supply administration pipe: one one be public electricity-using, is claimed to manage certainly by estate management like fire-fighting, feedwater, public, illumination, dredge pump etc.Comprise I and II loads such as fire-fighting, feedwater, elevator from pipe electricity part, supply power with double circuit so must be provided with, to satisfy the requirement of uninterrupted power supply.Wherein the underground garage switching station is provided with two high and low pressure systems of the using and the reserved to three of sub-district operated by rotary motion, is configured to 2 of 500KVA dry-type transformers from managing switching station, each 2 row of high and low voltage electric distribution screen, and construction investment is more than 5,000,000, and back-up system occupies generally.2 switching station distribution transformers are 2 1000KVA and do transformation in addition, invest bigger.This power supply quality is very reliable, and the power failure probability is very little, and stand-by power supply is close to idle, can not lack but invest a bit, but occupy a large amount of funds, and the wasting of resources is more.
Content of the present invention
The purpose of this invention is to provide a kind of uninterrupted power supply circuit, guaranteed under the situation of normal uninterrupted power supply, investment cost with engineering project economizes on resources.
The technical scheme that the present invention adopts is following:
A kind of uninterrupted power supply circuit; Comprise air switch, isolating switch and high-voltage dual power, described high-voltage dual power connects the duplex feeding line, is equipped with air switch and isolating switch on the duplex feeding line; High-voltage dual power other end out-put supply line is connected with transformer; Transformer out-put supply line is connected with many parallel branches, establishes at step down side simultaneously and outreaches circuit, outreaches and draws the siding that power supply of outreaching and low-voltage dual power are arranged on the circuit.
Connecting line is provided with air switch and isolating switch between described transformer and the high-voltage dual power.
Described transformer out-put supply line and many parallel branches carry out being in series with successively on the series line isolating switch, air switch and isolating switch.
Compared with present technology, beneficial effect of the present invention is following:
The present invention designs and adopts high-voltage dual power to implement that outage back stand-by power supply head end is hauled oneself willingly into or manually; Realize uninterrupted power supply; Save standby power system, establish one at step down side and outreach circuit, have a power failure simultaneously or during transformer fault in order to preceding two-way power supply; Draw with outreaching power supply and be connected to the siding of low-voltage dual power and outreach on the circuit, guarantee the reliability of supplying power.
Description of drawings
Fig. 1 is a structural representation of the present invention.
Embodiment
Referring to accompanying drawing, a kind of uninterrupted power supply circuit comprises air switch, isolating switch and high-voltage dual power 1; High-voltage dual power 1 connects the duplex feeding line; Be equipped with air switch and isolating switch on the duplex feeding line, high-voltage dual power 1 other end out-put supply line is connected with transformer 2, and transformer 2 out-put supply lines are connected with many parallel branches; Establish at step down side simultaneously and outreach circuit 3, outreach and draw the siding 4 that power supply of outreaching and low-voltage dual power are arranged on the circuit 3.Connecting line is provided with air switch and isolating switch between transformer 2 and the high-voltage dual power 1.Transformer 2 out-put supply lines and many parallel branches carry out being in series with successively on the series line isolating switch, air switch and isolating switch.
Claims (3)
1. uninterrupted power supply circuit; Comprise air switch, isolating switch and high-voltage dual power, it is characterized in that: described high-voltage dual power connects the duplex feeding line, is equipped with air switch and isolating switch on the duplex feeding line; High-voltage dual power other end out-put supply line is connected with transformer; Transformer out-put supply line is connected with many parallel branches, establishes at step down side simultaneously and outreaches circuit, outreaches and draws the siding that power supply of outreaching and low-voltage dual power are arranged on the circuit.
