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 photovoltaic SF6 breaker air pressure, photovoltaic battery array (11) are led by device
Line (7) connects photovoltaic rectifier (10), and photovoltaic rectifier (10), battery (5), inverter (1) are mutual by device conducting wire (7)
Connection, inverter (1) are separately connected SF6 pressure gauge (2), microprocessor (3), controlled switch (4), SF6 by device conducting wire (7)
Pressure gauge (2), microprocessor (3), controlled switch (4) are sequentially connected by signal wire (8), battery (5), controlled switch (4),
Breaker operator circuit (6) is sequentially connected by operation circuit conducting wire (9).
Photovoltaic battery array (11) is placed on open air, receives solar energy, converts solar energy into electrical energy；It is strong due to sunlight
It is not constant for spending, and the direct current for causing photovoltaic battery array (11) to issue is irregular, and photovoltaic rectifier (10) will be irregular
Direct current energy be converted into qualified direct current energy, be then stored in battery (5) or be transferred to inverter (1).
The direct current energy that battery (5), photovoltaic rectifier (10) export is converted AC energy by inverter (1).Inversion
Device (1) is respectively SF6 pressure gauge (2), microprocessor (3), controlled switch (4) offer working power by device conducting wire (7).
Battery (5) is that breaker operator circuit (6) provide work electricity by operation circuit conducting wire (9), controlled switch (4)
Source.
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 inverter (1) is used more herein, SF6 pressure gauge (2), microprocessor (3), controlled switch (4), stores
Battery (5), breaker operator circuit (6), device conducting wire (7), signal wire (8), operation circuit conducting wire (9), photovoltaic rectifier
(10), the terms such as photovoltaic battery array (11), but it does not exclude the possibility of using other terms.It is only using these terms
In order to be more convenient to describe and explain the essence of the utility model, being construed as any additional limitation all is and this
Utility model spirit is disagreed.
