Description
Technical field
The utility model relates to electrical equipment technical field, in particular to a kind of dual power supply switching equipment.
Background technique
Cannot be powered off when the operation of many important equipments, once power-off may cause important production accident or
Great loss, general we can provide backup power source for these equipment, but there are also the equipment of minority even the short time
Power-off is all not all right, leads to loss of data or disabler in the moment of power-off, cannot be continuous after reclosing backup power source
Movement before power-off.
Utility model content
The technical problem to be solved by the present invention is to provide one kind can auto switching electric source, and switching phase when power is off
Between the dual power supply switching equipment that does not power off.
The technical solution of the utility model are as follows:
A kind of dual power supply switching equipment, including electromagnetic relay, normal power supplies node, backup power source node, outlet line
Node, transformer and battery group, the normal power supplies node, backup power source node are respectively connected to the normally opened of electromagnetic relay
The transformer input point of contact and normally-closed contact, the transformer is connect with normal power supplies node, transformer output point and electromagnetism
The coil input contact connection of relay；The electric current output contact of the electromagnetic relay charging contact with battery group respectively
It is connected with outlet line node；The transformer earth wire contact of the transformer, the coil earth wire contact of the electromagnetic relay, institute
The battery group earth wire contact for stating battery group is connected to ground wire.
Further, battery group is minimum bears outlet line node normal output power 5-8S.
Further, battery group is connected in series using polymer lithium storage battery.
Further, electromagnetic relay uses high power relay, model JQX-40F-1Z.
Further, transformer output point output voltage is 12V or 36V.
The utility model has the beneficial effect that
The utility model can automatically switch backup power source when power-off, and will not break during switching
Electricity ensure that the sustainable supply of electric current, suitable for regions such as the protections of important equipment or circuit, such as computer room.But due to
Time interval down to switching route is to be powered by battery group, therefore this just determines that the power of main line can not
Can be too big, not so battery group can not provide enough power supplies in Switching power section.
Detailed description of the invention

In figure: 1- normal power supplies node, 2- backup power source node, 3- outlet line node, 4- ground wire, a1- transformer are defeated
Access point, a2- transformer output point, a3- transformer earth wire contact, b1- normally opened contact, b2- normally-closed contact, the touching of b3- coil ground wire
Point, b4- coil input contact, b5- electric current output contact, c1- charging contact, c2- battery group earth wire contact.
Specific embodiment
Specific embodiment of the present utility model is described further with reference to the accompanying drawing.It should be noted that
The explanation of these embodiments is used to help to understand the utility model, but does not constitute the restriction to the utility model.This
Outside, technical characteristic involved in the various embodiments of the present invention described below is as long as they do not conflict with each other
It can be combined with each other.
As shown in Figure 1:
A kind of dual power supply switching equipment, including electromagnetic relay, normal power supplies node 1, backup power source node 2, output line
Circuit node 3, transformer and battery group, the normal power supplies node 1, backup power source node 2 are respectively connected to electromagnetic relay
Normally opened contact b1 and normally-closed contact b2, the transformer input point a1 of the transformer connect with normal power supplies node 1, transformer
The coil of output point a2 and electromagnetic relay inputs contact b4 connection；The electric current output contact b5 of the electromagnetic relay respectively with
The charging contact c1 and outlet line node 3 of battery group are connected；Transformer earth wire contact a3, the electromagnetism of the transformer
The coil earth wire contact b3 of relay, the battery group earth wire contact c2 of the battery group are connected to ground wire 4.
For the utility model in the case where normal power-up, transformer obtains normal power supply from normal power supplies node 1, and
And be the coil power supply in electromagnetic relay, the electric current output contact b5 and normally opened contact b1 of electromagnetic relay are connected, and once
It is battery group is first that outlet line node 3 provides of short duration continued power there is a situation where powering off, and electromagnetic relay exists
When normal power supplies node 1 powers off, transformer moment power loss leads to the coil losing electricity of electromagnetic relay, electromagnetic relay
Electric current output contact b5 and normally-closed contact b2 is connected, and backup power source node 2 is route continued power.
The utility model can automatically switch backup power source when power-off, and will not break during switching
Electricity ensure that the sustainable supply of electric current, suitable for regions such as the protections of important equipment or circuit, such as computer room.But due to
Time interval down to switching route is to be powered by battery group, therefore this just determines that the power of main line can not
Can be too big, not so battery group can not provide enough power supplies in Switching power section.
Specifically, the process electric current smooth transition in order to guarantee power supply switching, battery group is minimum to bear outlet line
Node normal output power 5-8S.
Specifically, battery group is connected in series using polymer lithium storage battery.
Specifically, when power supply line is excessive, electromagnetic relay uses high power relay, model JQX-40F-1Z, with
It carries high-power output and biggish electric current passes through.
Specifically, the coil execution in electromagnetic relay acts required voltage when using high-power magnetic relay
Also can be higher, transformer output point output voltage is 12V or 36V.
The embodiments of the present invention is explained in detail in conjunction with attached drawing above, but the utility model is not limited to be retouched
The embodiment stated.For a person skilled in the art, right in the case where not departing from the utility model principle and spirit
These embodiments carry out a variety of change, modification, replacement and modification, still fall in the protection scope of the utility model.
