Description
Technical field
The utility model relates to a kind of mine electric equipment apparatus for examination and repair, relates in particular to the personal protector of the unexpected incoming call of a kind of mine interruption maintenance.
Background technology
The used GG of China's mine, KY type ground high-voltage electrical equipment all have protective earthing device; the effect of this type of device is: when the examination and repair for high-pressure electric equipment; this earthing device is dropped into; just can open the cabinet door then and enter maintenance; when unexpected incoming call occurring; the ground protection of high pressure backup protection device is would trip at once, and the cutoff high power supply is guaranteed the safety of maintainer and equipment.
But because structural behaviour, the own characteristic of explosion-proof device for mine; BGP9L-6AK type high-tension apparatus, KBZ-400 type low-voltage equipment that the down-hole is commonly used; mains side own does not possess earthing device, does not have high pressure GSN electricity to show device yet; when the unexpected incoming call of the prominent chance of down-hole examination and repair for high-pressure equipment, just can't be grounded the function of protection, incoming call alarm.
In present mine inspection, comparatively safe for the own person, experienced down-hole electrician is temporarily with copper conductor of three-phase binding post colligation, but result of use is bad and unreliable not attractive in appearance, causes the person to get an electric shock and injures and deaths easily during unexpected incoming call.
Summary of the invention
The purpose of this utility model provides the personal protector of the unexpected incoming call of a kind of mine interruption maintenance safe in utilization; this protector can be when down-hole high and low pressure electric equipment overhauls; be grounded the difunctional of protection and acousto-optic early warning, protect mine electrician's personal safety to greatest extent.
For achieving the above object, the technical solution adopted in the utility model is:
The personal protector of the unexpected incoming call of a kind of mine interruption maintenance, comprise in the middle of one phase grounding device and two limits acoustooptical electroscope mutually, it is characterized in that: middle phase grounding device comprises earth connection, and phase elastic force folder was in series with resistance in the middle of the earth connection two ends were electrically connected one respectively on the earth connection; Limit phase acoustooptical electroscope comprises limit phase elastic force folder, and phase elastic force folder in limit is electrically connected with the sound and light alarm parts by lead.
According to the personal protector of the unexpected incoming call of described mine interruption maintenance, it is characterized in that: the trigger head that described lead two ends are electrically connected described sound and light alarm parts respectively and described limit be the chuck of elastic force folder mutually.
According to the personal protector of the unexpected incoming call of described mine interruption maintenance, it is characterized in that: described earth connection is the soft copper lead of band sheath, and described lead is a copper conductor.
When using the utility model maintenance electric equipment, earlier the centre that middle the phase elastic force folder at earth connection two ends is clipped in electric equipment (high-tension apparatus/low-voltage equipment) respectively join on the terminal with the switch earth connection on, the limit phase elastic force that then two covers is connected with the sound and light alarm parts presss from both sides the A that is clipped in electric equipment respectively to be gone up mutually with C mutually, just can implement electric service work after all clipping.
In maintenance process, if the unexpected suddenly incoming call of last level power supply, having following two kinds of results can take place:
The one, phase grounding device single-phase earthing in the middle of network system is passed through, the detection of electrical leakage unit of protector detects ground signalling, the protector would trip, the loop of cutting off the electricity supply is to guarantee personal safety.
The 2nd, earth current is less, the protector tripping, and the three-phase binding post is charged; be clipped in the two cover sound and light alarm parts that A, B go up mutually this moment and can send the caution sound of " dripping " at once; and the flash red warning lamp, remind the maintenance electrician that electricity has been arranged herein, must be at once away from electrified body.
Protection in advance and acousto-optic early warning when the utility model can be realized unexpected the incoming call effectively protect the mine electrician to avoid electric shock.
