Description
Technical field
The present invention relates to rubber product more particularly to a kind of high-strength rubber skins that telescopicing performance is high.
Background technology
Double power-supply automatic transferring control switch widely exists on the market.It is one kind can in common power supply and
The switch of automatic conversion is carried out between stand-by power supply.It is by one or more transfer switching equipments and other necessary electric appliance groups
At for detection circuit, and when common power supply breaks down, by double power supply automatic transfer switch, automatically by load turn
It changes on stand-by power supply, uses electric equipment energy normal operation.It is that a kind of safe and reliable, automation, use scope are more and more wider
General is electrical.
But there is also such situations, that is, stand-by power supply also fails so consequence will be hardly imaginable.Therefore it needs
A kind of new technical solution is provided to solve such technical problem.
Invention content
The present invention overcomes the shortcomings of that background technology provides three power supply automatic conversion control systems of elevator, designs and develops this system
Purpose, provide three-way power to the load of elevator and be powered, when power supply power-fail all the way, remaining two-way is powered side by side, when two
Road power supply power-fail, remaining appoints all the way can so power, but the case where two-way power down simultaneously is quite few, and three roads are fallen simultaneously
Electricity is substantially impossible, is more improved to the security and stability of the present apparatus.
The present invention provides following technical proposals：Three power supply automatic conversion control systems of elevator, including main circuit module,
Control circuit module, the main circuit module contains the first power supply lead wire 1, second source lead 2, third power supply lead wire 3, described
First power supply lead wire 1, second source lead 2, third power supply lead wire 3 are connect with load end 4, first power supply lead wire 1
It is equipped with first contactor 5 in circuit, is equipped with second contactor 6 in the circuit of the second source lead 2, the third power supply draws
Third contactor 7 is equipped in the circuit of line 3, the control circuit module contains first control circuit 8, second control circuit 9, the
Three control circuits 10, the first control circuit 8 control the opening and closing of the first contactor 5, and the second control circuit 9 controls institute
The opening and closing of second contactor 6 is stated, the third control circuit 10 controls the third contactor 7 and is opened and closed.
Fuse 11 is equipped in the main circuit module, control circuit module.
The time relay 12 is equipped in the control circuit module.
Beneficial effects of the present invention：Open KT1-1 so that first contactor 5, second contactor 6, third contactor 7
Contacting, the first power supply lead wire 1, second source lead 2,3 three-way power of third power supply lead wire while powered operation, three protect
Danger.Three-way power is provided to the load of elevator to be powered, when power supply power-fail, remaining two-way are powered side by side all the way, when two-way electricity
Source power down, remaining appoints all the way can so power, but the case where two-way power down simultaneously is quite few, three tunnels while power down base
It is not possible that, more improved to the security and stability of the present apparatus in sheet.
Description of the drawings
Fig. 1 is the structural schematic diagram of the present invention.
Specific implementation mode
Below in conjunction with attached drawing, the invention will be further described with specific embodiment.
In Fig. 1：First power supply lead wire 1, second source lead 2, third power supply lead wire 3, load end 4, first contactor 5,
Second contactor 6, third contactor 7, first control circuit 8, second control circuit 9, third control circuit 10, fuse 11,
The time relay 12.
Elevator three power supply automatic conversion control systems, including main circuit module, control circuit module, the main circuit mould
Block contains the first power supply lead wire 1, second source lead 2, third power supply lead wire 3, and first power supply lead wire 1, second source draw
Line 2, third power supply lead wire 3 are connect with load end 4, and first contactor 5, institute are equipped in the circuit of first power supply lead wire 1
It states and is equipped with second contactor 6 in the circuit of second source lead 2, being equipped with third in the circuit of the third power supply lead wire 3 contacts
Device 7, the control circuit module contain first control circuit 8, second control circuit 9, third control circuit 10, first control
Circuit 8 processed controls the opening and closing of the first contactor 5, and the second control circuit 9 controls the opening and closing of the second contactor 6, described
Third control circuit 10 controls the third contactor 7 and is opened and closed.
Fuse 11 is equipped in the main circuit module, control circuit module.
The time relay 12 is equipped in the control circuit module.
Dual power supply and double circuit power supply, it is the same thing that people, which are generally considered that, is obscured mutually.But in fact have
Some differences.Three power supply power supplies are to draw three power supplys, are all connected with load and are powered.One of them or two power supplys are disconnected
Third power supply will not power off simultaneously after electric, can meet the power supply of one or two stage loads.
The circuit diagram that the three power supply automatic conversion control systems of elevator of the present embodiment use are illustrated in Fig. 1, is opened
KT1-1 so that first contactor 5, second contactor 6, third contactor 7 contacting, the first electricity of power supply lead wire 1, second
Source lead 2,3 three-way power of third power supply lead wire while powered operation, three insurances.
