Description
Technical field
The utility model relates to underground coal mine high-tension switch cabinet electrocution-proof protection technology, specifically a kind of underground coal mine high pressures
Switchgear shock preventing protector of electric.
Background technique
Currently, service personnel gets an electric shock in order to prevent, often when carrying out enabling maintenance to underground coal mine high-tension switch cabinet
Shock preventing protector of electric is installed on underground coal mine high-tension switch cabinet.However under prior art conditions, shock preventing protector of electric
Since self structure is limited, there are the following problems: the power supply of existing shock preventing protector of electric is taken from underground coal mine high voltage supply
System, once therefore underground coal mine high voltage supply system break down, the power supply of shock preventing protector of electric will occur therewith therefore
Barrier, thus causes it to lose electrocution-proof protection function.Based on this, it is necessary to a kind of completely new shock preventing protector of electric is invented, with
Existing underground coal mine high-tension switch cabinet shock preventing protector of electric is solved to lose when underground coal mine high voltage supply system breaks down
The problem of electrocution-proof protection function.
Summary of the invention
The utility model is in order to solve existing underground coal mine high-tension switch cabinet shock preventing protector of electric in underground coal mine high pressure
The problem of electrocution-proof protection function is lost when power supply system breaks down provides a kind of underground coal mine high-tension switch cabinet protection against electric shock
Protective device.
The utility model adopts the following technical scheme that realization:
A kind of underground coal mine high-tension switch cabinet shock preventing protector of electric, including underground coal mine high-tension switch cabinet, the first electric power storage
Pond, the second battery, the first vacuum contactor, the second vacuum contactor, microswitch, button switch, photoelectrical coupler；
Wherein, the first battery, the second battery, the first vacuum contactor, the second vacuum contactor, microswitch, light
Electric coupler is mounted on the inner cavity of underground coal mine high-tension switch cabinet；The drive rod and underground coal mine high-tension switch cabinet of microswitch
Cabinet door connection；Button switch, which runs through, to be installed in the cabinet door of underground coal mine high-tension switch cabinet；The anode of first battery is successively
It is connected by the positive input terminal of microswitch, button switch and photoelectrical coupler；The cathode and photoelectrical coupler of first battery
Negative input end connection；The anode of second battery is connect with the positive output end of photoelectrical coupler；The cathode one of second battery
Aspect is connected by the coil of the first vacuum contactor and the negative output terminal of photoelectrical coupler, is on the other hand connect by the second vacuum
The coil of tentaculum and the negative output terminal of photoelectrical coupler connect；The normally opened contact of first vacuum contactor is serially connected with underground coal mine height
It compresses switch on the power supply firewire of cabinet；The normally opened contact of second vacuum contactor be serially connected with underground coal mine high-tension switch cabinet for electrical zero
On line.
Specific work process is as follows: one, when to underground coal mine high-tension switch cabinet carry out enabling maintenance, underground coal mine high pressure
The cabinet door of switchgear is opened, and microswitch is driven to disconnect.At this point, photoelectrical coupler power loss, the coil of the first vacuum contactor
With the equal power loss of coil of the second vacuum contactor, the normally opened touching of the normally opened contact of the first vacuum contactor and the second vacuum contactor
Point disconnects, thus the power supply firewire and the power supply equal power loss of zero curve of underground coal mine high-tension switch cabinet prevent service personnel from getting an electric shock.
Two, after overhauling, service personnel closes the cabinet door of underground coal mine high-tension switch cabinet, and presses button switch, cabinet door driving
Microswitch closure.At this point, photoelectrical coupler obtains electric, the coil of the coil of the first vacuum contactor and the second vacuum contactor is equal
Must be electric, the normally opened contact of the normally opened contact of the first vacuum contactor and the second vacuum contactor is closed, and underground coal mine height presses off
Close cabinet power supply firewire and power supply zero curve it is electric, thus underground coal mine high-tension switch cabinet starts to work normally.
Based on the above process, compared with existing underground coal mine high-tension switch cabinet shock preventing protector of electric, the utility model institute
A kind of underground coal mine high-tension switch cabinet shock preventing protector of electric stated realizes underground coal mine height and presses off by using brand new
The electrocution-proof protection of cabinet is closed, power supply is no longer derived from underground coal mine high voltage supply system, but uses independent battery (first
Battery, the second battery), therefore even if underground coal mine high voltage supply system breaks down, the power supply of the utility model is not yet
It can break down, the normal operation of electrocution-proof protection function has thus been effectively ensured.
The utility model is structurally reasonable, ingenious in design, efficiently solves existing underground coal mine high-tension switch cabinet protection against electric shock and protects
Protection unit loses the problem of electrocution-proof protection function when underground coal mine high voltage supply system breaks down, and is suitable for underground coal mine
High-tension switch cabinet.
