Description
Technical field
The utility model relates to a kind of automatic devices, more particularly, to a kind of low automatic opening operation of SF6 breaker air pressure
Power supply device.
Background technique
In grid operation, SF6 breaker is using sulfur hexafluoride (SF6) gas as arc-extinguishing medium and dielectric
A kind of breaker.When SF6 breaker SF6 pressure is lower than locking value, the dielectric strength of SF6 breaker, the decline of arc extinguishing ability, to setting
Standby safe operation, which is brought, to be seriously threatened.
Breaker operator circuit, also known as breaker control circuit, effect is: being carried out by secondary circuit to breaker
Switching on and off operation.It is disconnected according to " State Grid Corporation of China's power transformation operation management regulation " the 2nd fascicle when SF6 pressure is lower than locking value
Road device O&M detailed rules and regulations, it is desirable that power transformation operation maintenance personnel reports regulation personnel on duty immediately, disconnects SF6 circuitbreaker control power supply.
Currently, power supply company sends power transformation operation maintenance personnel to go live disconnection when SF6 breaker SF6 pressure is lower than locking value
SF6 circuitbreaker control power supply consumes manpower and spends and go the distance time of substation than more serious, and can not break in time
Open SF6 circuitbreaker control power supply.
Utility model content
In order to save manpower and disconnect SF6 circuitbreaker control power supply in time, the utility model provides SF6 breaker gas
Force down automatic opening operation power supply device.
The technical scheme adopted by the utility model to solve the technical problem is as follows: the low automatic disconnection behaviour of SF6 breaker air pressure
Make power supply device, including installation's power source, SF6 pressure gauge, microprocessor, controlled switch, operation circuit power supply, breaker operator return
Road, device conducting wire, signal wire, operation circuit conducting wire, it is characterized in that: installation's power source is separately connected SF6 pressure by device conducting wire
Table, microprocessor, controlled switch, SF6 pressure gauge, microprocessor, controlled switch are sequentially connected by signal wire, operation circuit electricity
Source, controlled switch, breaker operator circuit are sequentially connected by operation circuit conducting wire.
The utility model has the beneficial effects that the low automatic opening operation power supply device of SF6 breaker air pressure, when SF6 open circuit
It is automatic to disconnect SF6 circuitbreaker control power supply when device SF6 pressure is lower than locking value, manpower is saved, it is disconnected that SF6 can be disconnected in time
Road device operation power.
Detailed description of the invention
The present invention will be further described with reference to the accompanying drawings and examples.
Fig. 1 is the structural schematic diagram of the low automatic opening operation power supply device of SF6 breaker air pressure.
In figure, 1 --- installation's power source;2 --- SF6 pressure gauge;3 --- microprocessor;4 --- controlled switch;5 --- behaviour
Make ring current;6 --- breaker operator circuit;7 --- device conducting wire;8 --- signal wire;9 --- operation circuit conducting wire.
Specific embodiment
It is specific embodiment of the utility model and in conjunction with attached drawing below, the technical solution of the utility model is made further
Description, but the utility model is not limited to these examples.
The low automatic opening operation power supply device of SF6 breaker air pressure, including installation's power source (1), SF6 pressure gauge (2), micro- place
Manage device (3), controlled switch (4), operation circuit power supply (5), breaker operator circuit (6), device conducting wire (7), signal wire (8),
Operation circuit conducting wire (9), installation's power source (1) by device conducting wire (7) be separately connected SF6 pressure gauge (2), microprocessor (3), by
Control switch (4), SF6 pressure gauge (2), microprocessor (3), controlled switch (4) are sequentially connected by signal wire (8), operation circuit
Power supply (5), controlled switch (4), breaker operator circuit (6) are sequentially connected by operation circuit conducting wire (9).
Installation's power source (1) is respectively SF6 pressure gauge (2), microprocessor (3), controlled switch (4) by device conducting wire (7)
Working power is provided.Operation circuit power supply (5) is breaker operator circuit by operation circuit conducting wire (9), controlled switch (4)
(6) working power is provided.
Under normal circumstances, controlled switch (4) is in "on" position.Controlled switch (4), is normally closed switch, i.e., not outer
Power is in the switch of closed state in the case where acting on, stir when someone's toggle switch button or by automatic device control switch
When, switch conversion is off-state.
When the instruction of the SF6 pressure gauge (2) of SF6 breaker is lower than locking value, then signal to microprocessor (3), micro- place
It manages to controlled switch (4) hair sub-gate signal after device (3) judge, controlled switch (4) separating brake disconnects the operation of SF6 breaker
Ring current (5) makes breaker operator circuit (6) power loss and cannot carry out switching on and off operation to breaker.
When the instruction of the SF6 pressure gauge (2) of SF6 breaker is higher than locking value, then do not signal to microprocessor (3), from
And microprocessor (3) does not send out signal any to controlled switch (4), controlled switch (4) automatically restores to "on" position, makes breaker
Operation circuit (6) charges and restores the function of operating to breaker switching on and off.
The specific embodiments described herein are merely examples of the spirit of the present invention.The utility model institute
Belonging to those skilled in the art can make various modifications or additions to the described embodiments or using similar
Mode substitute, but without departing from the spirit of the present application or beyond the scope of the appended claims.
Although be used more herein installation's power source (1), SF6 pressure gauge (2), microprocessor (3), controlled switch (4),
The arts such as operation circuit power supply (5), breaker operator circuit (6), device conducting wire (7), signal wire (8), operation circuit conducting wire (9)
Language, but it does not exclude the possibility of using other terms.The use of these items is only for be more convenient to describe and explain this
The essence of utility model, it is contrary to the spirit of the present invention to interpret them as any one of the additional limitations.
