Description
Technical field
The utility model relates to a kind of power circuit control system.In particular for the lock-in control system of the wind-powered electricity generation in mine and gas electricity.
Background technology
For preventing gas accident, ensure mine safety production, " safety regulations in coal mine ", AQ6201-2006 " coal mine safety monitoring system generic specifications " etc. propose strict demand to the gas electric shutting in coal production process and lock between air and electricity.When the booster of normal work shuts down or can cut off the power supply of whole non-intrinsically safe safe electrical apparatus in blowing-out district after blowing-out; Should be able to disconnect in digging laneway when gas exceeding limit or the whole non-intrinsically safe safe electrical apparatus of coal-face.
Along with the development of mechanization in recent years, extractive equipment power is increasing, and electric pressure also upgrades to 1140V thereupon, and in order to increase the power of winning equipment, digger employs 1140V power supply, and in mine, all the other equipment such as winch etc. uses 660V power supply.Once gas exceeding limit or methane transfinite in the blower fan blowing-out of normal work or mine, 660V power supply in tunnel should be disconnected, disconnect the 1140V power supply of development machine again.But the circuit breaker generally used at present is only applicable to control 660V electric pressure switch, uncontrollable 1140V power supply.If the driving face of mine is apart from too far away, simultaneously far away apart from electric substation, when driving can not meet the demands to powering during the second half section, now can only mobile substation be moved on in digging laneway, therefore also needing to cut off this driving face 6KV substation line power supply.So, the ventilation safety monitoring system in mine becomes relative complex.
Utility model content
In order to solve the problem, the utility model provides a kind of mine wind-powered electricity generation and gas electric shutting control system, comprise outstation, for the treatment of information and sending controling instruction, be connected to vacuum feed switch, high-voltage vacuum distribution equipment, circuit breaker, fan monitor device, firedamp sensor, methane transducer with outstation.
Described fan monitor device is arranged on blower fan, for detecting the duty of blower fan, and blower fan work state information is sent to outstation.
Described firedamp sensor and methane transducer are arranged in mine, for detecting gas in mine air and methane content, and the information detected are sent to outstation.
Described vacuum transducer, high-voltage vacuum distribution equipment, circuit breaker arrange in power circuit, for controlling cut-offfing of power circuit.
Mine wind-powered electricity generation as above and gas electric shutting control system, further illustrate into, described vacuum transducer is arranged in 1400V power circuit, for cut-offfing of control 1400V power circuit; Described high-voltage vacuum distribution equipment is arranged in 6KV power circuit, for cut-offfing of control 6KV power circuit; Described circuit breaker is arranged in 660V power circuit, for cut-offfing of control 660V power circuit.
Mine wind-powered electricity generation as above and gas electric shutting control system, further illustrate into, outstation is also connected with remote control center, for the long-range work checked and control outstation; Remote control center is provided with warning system.
Beneficial effect:
What the utility model only needed to adopt a set of monitoring system just can complete multiple high-tension circuit cut-offs monitoring work.
The utility model can monitor blower fan running status in mine, gas and the aerial content of methane in mine can be monitored, if there is blower fan to stop transport, gas or methane transfinite, automatically can cut off the power supply of all non-intrinsically safe safe electrical apparatus in region, the circuit cut off comprises 1400V power circuit, 6KV power circuit, 660V power circuit.The utility model further enhancing the safety factor of mine.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation.
Detailed description of the invention
Vacuum transducer of the present utility model is KBZ-400 type feeding switch, is arranged in 1400V power circuit, for cut-offfing of control 1400V power circuit.
High-voltage vacuum distribution equipment is high-voltage vacuum distribution equipment PJG
43-200/6 high voltage safeguard switch; Be arranged in 6KV power circuit, for cut-offfing of control 6KV power circuit.
Circuit breaker selected by the utility model is D1 type circuit breaker, and D1 type circuit breaker is applicable to control feeding switch 660V tripping coil and magnetic switch 36V electromagnetic coil.D1 type circuit breaker is arranged in 660V power circuit, for cut-offfing of control 660V power circuit.
The outstation that the utility model is selected is KJF86N type outstation.
In normal operation, blower fan is in air-supply operating condition, and whether the operation that blower fan monitored in real time by fan monitor device is normal; Firedamp sensor, methane transducer monitor the content of gas and methane in mine air in real time.
When fan monitor device monitor fan parking or air output obviously not enough time, outstation will control vacuum feed switch, high-voltage vacuum distribution equipment, circuit breaker immediately, disconnect 1400V power circuit, 6KV power circuit and 660V power circuit.
When firedamp sensor or methane transducer detect that in mine, gas bearing capacity or methane content transfinite, outstation will control vacuum feed switch, high-voltage vacuum distribution equipment, circuit breaker immediately, disconnect 1400V power circuit, 6KV power circuit and 660V power circuit.
While the above-mentioned work of execution, the blower fan stop information detected or gas, methane are transfinited information feed back to remote control center by outstation, and start warning system and report to the police.
After danger is removed, remote control center sends to outstation the instruction that switches on power, and outstation controls vacuum feed switch, high-voltage vacuum distribution equipment, circuit breaker, connects 1400V power circuit, 6KV power circuit and 660V power circuit.Recover electric equipment in mine normally to work.
Above-mentioned is the explanation of the utility model examination example, does not represent the utility model protection domain.
