Abstract
The utility model belongs to a static transfer switch (STS) device with external replacement protection. The device comprises a static transfer switch STS, breakers K1, K2, and K3, power supply lines S1 and S2, and an output line OUTPUT. The device is characterized in that breakers K4 and K1 are connected on the power supply line S1, and breakers K5 and K2 are connected on the power supply line S2. Other ends of the breakers K4 and K5 are connected, and are connected with the breaker K3 and the output line OUTPUT. With the device provided by the utility model, when STS is damaged, enough reparation time is provided, and device reparation and replacement can be realized without power off. Therefore, a safety protection effect is provided, and the device is safe and reliable.
Description
Technical field
The utility model belongs to power supply unit, particularly a kind of quiet commentaries on classics (STS) device of changing protection for having of power devices such as computer, server is outside.
Background technology
Users such as present most computer, server are protected data center safety, all adopt the supply power mode of static conversion system two-way power supply, and this mode exists following problem: when the one, STS damages, can cause system-down, have the time difference of maintenance; The 2nd, when STS wears out or safeguards, need artificial the power failure to change.Can bring loss and trouble to the user like this.
Summary of the invention
The objective of the invention is to overcome above-mentioned technical deficiency, no matter provide a kind of under emergency maintenance and equipment replacement situation, can both guarantee outside quiet commentaries on classics (STS) device of changing protection of having of normal power supply.
The used technical scheme of the utility model technical solution problem is: a kind of quiet commentaries on classics (STS) device with outside replacing protection comprises Static Transfer Switch STS, circuit breaker K1, K2, K3, the S1 of supply line, S2 and outlet line OUTPUT; It is characterized in that connecting a circuit breaker K4 and K1 at the S1 of supply line, connect a circuit breaker K5 and K2 at the S2 of supply line, circuit breaker K4, the K5 other end connect and are connected with outlet line OUTPUT with circuit breaker K3.
The beneficial effects of the utility model are: this utility model gives abundant maintenance time when STS damages, and guarantees maintain and replace equipment under the situation of not cutting off the power supply, and has played the safeguard protection effect, makes device security reliable.
Description of drawings
Specify with embodiment below in conjunction with accompanying drawing.
Fig. 1 has the outside electrical schematic diagram of changing quiet commentaries on classics (STS) device of protection.
Among the figure: the STS-Static Transfer Switch; K1, K2, K3, K4, K5-circuit breaker; S1, S2-supply line; The OUTPUT-outlet line.
Embodiment
Embodiment, with reference to accompanying drawing, a kind of quiet commentaries on classics (STS) device with outside replacing protection comprises Static Transfer Switch STS, circuit breaker K1, K2, K3, the S1 of supply line, S2 and outlet line OUTPUT; It is characterized in that connecting a circuit breaker K4 and K1 at the S1 of supply line, connect a circuit breaker K5 and K2 at the S2 of supply line, circuit breaker K4, the K5 other end connect and are connected with outlet line OUTPUT with circuit breaker K3.The input 1 of Static Transfer Switch STS connects the other end of circuit breaker K1, and input 2 connects the other end of K2, and output 3 connects the other end of K3.
When Static Transfer Switch STS damaged, first cut-off breaker K3 disconnected K1 and K2 again, and STS breaks away from from system with Static Transfer Switch, and close circuit breaker K4 or K5 guarantee normal power supply.Need to safeguard or when changing that when Static Transfer Switch STS can not continue a journey the replacing Static Transfer Switch of can in time cut off the power supply STS, system is by the S2(of supply line or S1 under the landearth-circumstance condition of not cutting off the power supply) power supply powers circuit breaker K2 and K3(or K1 and K3) closure.When changing Static Transfer Switch STS, elder generation cut-off breaker K1(or K2), assurance is one tunnel power supply, close circuit breaker K5(or K4 then) the last allowance below nominal size of (needing to guarantee K5(or K4) is less than 2Vac), then at this moment cut-off breaker K3 and K2 can disassemble Static Transfer Switch STS.Safeguard or change finish after, first close circuit breaker K2 and K3(or K1 and K3), cut-off breaker K5(or K4 then), then close circuit breaker K1(or K2), finish the maintenance work of whole system.
Claims (1)
