Abstract
The utility model discloses a dual power supply transfer system which comprises a wiring busbar and an automatic transfer switch (ATS). The dual power supply ATS is provided with two input terminals and an output terminal. A wire is led out on the wiring busbar, and the wire is successively connected with a breaker QF1 and a current transformer BH1 in a series manner, and then is accessed to one of the input terminals of the automatic transfer switch (ATS). A wire is led out from the other input terminal of the automatic transfer switch (ATS) and then is externally connected with a generator after being successively connected with a current transformer BH2 and a breaker QF2 in a series manner. The output terminal of the automatic transfer switch (ATS) is led out via a wire. The electrical system of the utility model is simple in structure, reasonable in layout and long in service life, allows zero flashover to be realized, enables the power supply efficiency to be improved, and helps to improve a power supply environment.
Description
Technical field
The utility model relates to the low-voltage distribution cabinet field, is specifically related to a kind of GCK cabinet type duplicate supply switched system.
Background technology
In power distribution equipment, need realize two kinds of switchings between the power supply through the double loop power supply switching device shifter, the double loop power supply switching device shifter generally has two kinds: a kind of is STS (Static Transfer Switch), and static switch is STS again.Be power supply alternative automatic switchover system, STS automatically switched to the second road powering load after the first via broke down, and the words STS of the second tunnel fault automatically switches to first via powering load.Be suitable for UPS-UPS, the UPS-generator, the UPS-civil power, civil power-civil powers etc. are the conversion of not cutting off the power supply of two-way power supply arbitrarily.The static diverter switch of STS is mainly by the Based Intelligent Control plate, high-speed thyristor, and circuit breaker constitutes. and its standard be≤8ms not cause the load of IT class to cut off the power supply switching time.Both load was reliably supplied power, and can guarantee the fail safe of STS when difference is switched mutually simultaneously again.
Another kind is ATS (Automatic transfer switching equipment), automatic change-over.ATS mainly is used in emergency power supply system, with the device for switching of load circuit from an automatic changing-over of power supply to another (subsequent use) power supply, to guarantee that important load is continuous, reliability service.ATS is a mechanical structure, and be more than 100 milliseconds change-over time, can cause the load outage.Be fit to illumination, electric machinery load.Automatic change-over adopts biserial combined type contact, sliding mechanism, electrical micro-machine energy pre-storage and microelectronics control technology, has realized zero arcing basically.Drive motors is a neoprene latex insulation damp-heat type motor, and safety device automatic trip when exceeding 110 ℃ of temperature and overcurrent condition is housed.Pending fault is promptly devoted oneself to work after disappearing automatically, has largely guaranteed switch life.
The utility model content
The purpose of the utility model provides a kind of duplicate supply switched system, adopts the core component of automatic change-over ATS as the double loop power supply switching device shifter, improves power supplying efficiency, improves the power supply environment.
The technical scheme of the utility model is following:
A kind of duplicate supply switched system; Include line bank and automatic transfer switch ATS; Described duplicate supply ATS switch has two inputs and an output; It is characterized in that: draw wiring from described line bank, be connected in series an input that inserts automatic transfer switch ATS behind the circuit breaker Q F1 summation current transformer 1TA in the described wiring successively; Draw wiring from another input of said automatic transfer switch ATS, and external generator behind series current instrument transformer 2TA and the circuit breaker Q F2 successively; The output of said automatic transfer switch ATS has wiring to draw.
Described duplicate supply switched system is characterized in that: bus row is adopted in described wiring.
The beneficial effect of the utility model:
The utility model electrical system architecture is simple, and is rationally distributed, realized zero arcing, and long service life has improved power supplying efficiency, has improved the power supply environment.
Description of drawings
Fig. 1 is the electrical structure sketch map of the utility model.
Embodiment
Referring to Fig. 1; A kind of duplicate supply switched system; Include line bank and automatic transfer switch ATS; Duplicate supply ATS switch has two inputs and an output, draws wiring from line bank, is connected in series an input that inserts automatic transfer switch ATS behind the circuit breaker Q F1 summation current transformer 1TA in the wiring successively; Draw wiring from another input of automatic transfer switch ATS, and external generator behind series current instrument transformer 2TA and the circuit breaker Q F2 successively; The output of automatic transfer switch ATS has wiring to draw.
Further, bus row is adopted in wiring.
Claims (2)
1. duplicate supply switched system; Include line bank and automatic transfer switch ATS; Described duplicate supply ATS switch has two inputs and an output; It is characterized in that: draw wiring from described line bank, be connected in series a primary power cource input that inserts automatic transfer switch ATS behind the circuit breaker Q F1 summation current transformer 1TA in the described wiring successively; Draw wiring from another stand-by power supply input of said automatic transfer switch ATS, and external generator behind series current instrument transformer 2TA and the circuit breaker Q F2 successively; The output of said automatic transfer switch ATS has wiring to draw.
2. duplicate supply switched system according to claim 1 is characterized in that: bus row is adopted in described wiring.
