Description
Technical field
The present invention relates to electric power apparatus examination safety appliance technical fields, prevent more particularly, to low-voltage air switch is dedicated
Maloperation lockset.
Background technique
Air switch is very important a kind of electric appliance in substation's low-voltage AC/DC system, for electrically setting for substation
It is standby that control or electrical source of power are provided.When having service work on the electrical equipment in substation, operation maintenance personnel should be according to live feelings
Condition reasonable Arrangement safety measure, situations such as rotating suddenly in order to avoid the reverse charge, the motor that are likely to occur in maintenance process, cause
Wounding event, some air switch (such as voltage transformer secondary air switch, disconnecting switch control or electrical source of power air switches
Deng) should be disconnected, " do not switch on, men working should be also hung on air switch！" nameplate.Above-mentioned work is referred to as " two
Secondary peace is arranged ", on the one hand safety instruction can be played the role of to operating personnel by doing so, on the other hand can be to avoid overhauling
Air switch is misused energization in journey, prevents from causing into all kinds of person or equipment safety accident.
Currently, reliability and continuity in order to guarantee system power supply, the service work of substation is often according to power failure
Plan, timesharing are conducted batch-wise, and when arranging that the secondary peace of air switch is arranged, often have maintenance interval device and interval device
Situation in same screen cabinet.To arrange that secondary peace is arranged in this case, the processing method that operation maintenance personnel generallys use has:
First is that live special messenger's monitoring, second is that insulating tape is pasted on the corresponding air switch of maintenance interval, third is that in air switch
Upper suspension " No switching on, someone's work " nameplate, but these three modes have shortcoming.
As power grid construction develops rapidly, substation is being in the process that normal station changes to intelligent station, live inspection
It is more to repair project under construction, staff is more miscellaneous, and O&M duty personnel is less.And this mode is guarded for special messenger, then very
Labor intensive, operation maintenance personnel whole scene monitoring difficult to realize, if care provider not can be carried out safety supervision because of thing, work is just
It need to stop immediately, leverage working efficiency.It is equipped with for situation with present workload and Field Force, this safety is arranged
It applies and does not have real isolation effect at all.
Therefore, it is necessary to study a kind of new anti-misoperation lockset for low-voltage air switch.
The utility model of Publication No. CN203225180U discloses a kind of fool proof Sign Board of air switch, solution
It has determined not eye-catching enough the problem of existing air switch sign board.Including air switch (1), in the face of air switch (1)
It is provided on plate light emitting diode (6), light emitting diode (6) is connected by human body infrared detection sensitive switch (7) and power supply (8)
It is logical, it is provided with rear glass frame (5) on front side of light emitting diode (6), is provided with observation glass on front side of rear glass frame (5)
Glass frame (3) is provided with Sign Board card slot (4) between rear glass frame (5) and observation instrument bezel (3), in Sign Board card slot (4)
Middle activity is plugged with Sign Board.It is particularly suitable for using on the air switch control flow in substation.The utility model is using mark
The mode for knowing board places maloperation, easy to fall off, can not fundamentally solve the case where maloperation.
The utility model patent of Publication No. CN206040502U discloses a kind of air switch anti-misoperation protective cover, packet
Perpendicular baffle is included, the upper end of perpendicular baffle is vertically and fixedly provided with snap-gauge, and lower end is ipsilateral to be vertically and fixedly provided with lower snap-gauge；Outside the perpendicular baffle
Side is equipped with photoelectric sensor, and photoelectric sensor is connected to control circuit, and control circuit is equipped with alarm.Although this is practical
Exposed air switch is closed by the novel mode with buckle, avoids nameplate suspension inconvenience, caducous
Problem effectively avoids the occurrence of false switching is gone；Be arranged alarm remind staff, further ensure equipment and
Personal safety.But the utility model does not account for the space problem of low-voltage air switch, and by the way of sensor
Additional power supply is needed, using not being too convenient.
Summary of the invention
In view of this, that in view of the deficiencies of the prior art, it is an object of the present invention to provide a kind of low-voltage air switch is dedicated anti-
Only maloperation lockset is made full use of the structure chart feature for carrying two apertures on low-voltage air switch, is locked using U-shaped hook pawl
Only, the appearance of unexpected combined floodgate situation can effectively be prevented by not needing live special messenger's monitoring.
In order to achieve the above objectives, the invention adopts the following technical scheme:
