The spare power automatic switching device additionally has a voltage switching function under a double-bus connection method and can achieve self adaptation of an incoming line power supply, and the incoming line power supply can be changed into three power supplies from double power supplies.

Description

Double-bus three supply self adaptation backup auto-activating devices

Technical field

The utility model relates to a kind of double-bus three supply self adaptation backup auto-activating devices.

Background technology

Because traditional backup auto-activating device (stand-by power supply drops into operative installations automatically) all adopts the link mode, for single busbar connection or single mother partition mode of connection almost without impact, but under the double bus scheme mode, mode is switched more frequent, inlet wire one operation and a bus, when switching, when another bus, prepared auto restart just can not correct operation, the reliability that impact is powered.On the contrary, inlet wire two operations and a bus, when switching and another bus, prepared auto restart can not correct operation.When three power supplys are realized prepared auto restart, a backup auto-activating device can not be realized.So need development double-bus three supply self adaptation prepared auto restarts, with the reliability of raising power supply and the flexibility of prepared auto restart mode.

The utility model content

The purpose of this utility model is to provide a kind of double-bus three supply self adaptation backup auto-activating devices of applicable double-bus three Power Supplies Condition, can increase the operational mode of backup auto-activating device and the flexibility of application, thereby improves the reliability for electricity consumption.

A kind of double-bus three supply self adaptation backup auto-activating devices, comprise the first inlet wire, the second inlet wire and the 3rd inlet wire, its special feature is: also comprise the first bus and the second bus, wherein the first bus is connected with the first inlet wire with the first circuit breaker by No. 1 disconnecting link of the first bus of series connection, this first bus also is connected with the second inlet wire with the second circuit breaker by No. 2 disconnecting links of the first bus of series connection, and this first bus also is connected with the 3rd inlet wire with the 3rd circuit breaker by No. 3 disconnecting links of the first bus of series connection; Wherein the second bus is connected with the first inlet wire with the first circuit breaker by No. 1 disconnecting link of the second bus of series connection, this second bus also is connected with the second inlet wire with the second circuit breaker by No. 2 disconnecting links of the second bus of series connection, and this second bus also is connected with the 3rd inlet wire with the 3rd circuit breaker by No. 3 disconnecting links of the second bus of series connection.

Wherein also comprise the 4th circuit breaker, the 4th circuit breaker is connected between the first bus and the second bus.

The utlity model has following effect: 1, backup auto-activating device of the present utility model has increased voltage switching function under the double bus scheme mode, can realize the self adaptation of incoming power; 2, backup auto-activating device incoming power of the present utility model can increase to three power supplys by duplicate supply; 3, backup auto-activating device of the present utility model is safe and reliable to operation, has met the demand of on-the-spot various operational modes.

The accompanying drawing explanation

Accompanying drawing 1 is circuit theory diagrams of the present utility model.

Embodiment

As shown in Figure 1, the utility model is a kind of double-bus three supply self adaptation backup auto-activating devices, comprise the first inlet wire UX1, the second inlet wire UX2 and the 3rd inlet wire UX3, also comprise the first bus L1 and the second bus L2, wherein the first bus L1 is connected with the first inlet wire UX1 with the first circuit breaker 1DL by No. 1 disconnecting link 11G of the first bus of series connection, this first bus L1 also is connected with the second inlet wire UX2 with the second circuit breaker 2DL by No. 2 disconnecting link 12G of the first bus of series connection, and this first bus L1 also is connected with the 3rd inlet wire UX3 with the 3rd circuit breaker 3DL by No. 3 disconnecting link 13G of the first bus of series connection, wherein the second bus L2 is connected with the first inlet wire UX1 with the first circuit breaker 1DL by No. 1 disconnecting link 21G of the second bus of series connection, this second bus L2 also is connected with the second inlet wire UX2 with the second circuit breaker 2DL by No. 2 disconnecting link 22G of the second bus of series connection, and this second bus L2 also is connected with the 3rd inlet wire UX3 with the 3rd circuit breaker 3DL by No. 3 disconnecting link 23G of the second bus of series connection.Wherein also comprise the 4th circuit breaker 4DL, the 4th circuit breaker 4DL is connected between the first bus L1 and the second bus L2.

According to the difference of operational mode, backup auto-activating device of the present utility model is designed with 4 kinds of operational modes, and the mode that articulates of inlet wire is the isolation switch position automatic decision according to this circuit by backup auto-activating device.

Operational mode inlet wire UX1, the second inlet wire UX2 standby throwing each other in 1: the first; Operational mode inlet wire UX1, the 3rd inlet wire UX3 standby throwing each other in 2: the first; Operational mode inlet wire UX2, the 3rd inlet wire UX3 standby throwing each other in 3: the second; Operational mode 4: the first inlet wire UX1, the second inlet wire UX2 run on respectively a bus, and mother is standby throws.

These 4 kinds of modes are controlled by hard pressing plate, when a certain mode is moved, drop into the corresponding hard pressing plate of this mode, exit other 3 kinds of hard pressing plates of mode.If certain section busbar overhaul, drop into corresponding busbar overhaul pressing plate, the bus that drops into the maintenance pressing plate does not participate in the differentiation of prepared auto restart logic.
