Abstract
The utility model relates to a control circuit for a methane gas monitoring power-off device, which comprises an electronically controlled main-transformer and a methane gas monitoring power-off device, and is characterized in that the circuit is provided with a rechargeable energy-storage type power supply, wherein the input end of the rechargeable energy-storage type power supply is connected to one output end of the electronically controlled main-transformer and the other end of that is connected to the input end of the methane gas monitoring. By adopting the circuit, the continuous monitoring on methane gas can be realized when the electronically controlled main-transformer of a coal winning machine has no power supply.
Description
Technical field
The utility model relates to a kind of control circuit, especially a kind of circuit to the gas monitor non-stop run.
Background technology
Cutoff instrument does not have power source special in design, being after leaning on the charged work of coal-winning machine, provides power supply by control transformer, relay output switching signal behind the cutoff instrument collection gas density signal, the start-stop situation of control coal-winning machine.The automatically controlled part master control of coal-winning machine transformer has electricity, and master control transformer output 12V alternating current output intrinsic safety 12V power supply after intrinsic safety electric source is handled is supplied with cutoff instrument, and cutoff instrument is established the beginning initial work by cable; When confirming that gas density does not exceed standard, cutoff instrument collects normal signal, the output connection signal; Coal-winning machine continues operation, and when confirming that gas density exceeds standard, cutoff instrument collects fault-signal; The output cut-off signal, the coal-winning machine outage is out of service.
Adopt said system to have only coal-winning machine under the charging operation state; Cutoff instrument could be worked, and under coal-winning machine outage stopped status, cutoff instrument does not have; Can not carry out continuous monitoring monitoring harmony light alarm to gas density, security incident takes place when gas density exceeds standard easily.
Summary of the invention
The purpose of the utility model provides a kind of circuit that gas density is carried out continuous monitoring, and economical and practical, technology is simple.
The utility model is realized in the following manner: a kind of gas monitor cutoff instrument control circuit; Comprise automatically controlled main transformer, gas monitor cutoff instrument; This circuit is provided with a charging accumulate formula power supply; The input of charging accumulate formula power supply is connected an output of automatically controlled main transformer, and output is connected with gas monitor cutoff instrument input, and another output of automatically controlled main transformer is connected with the input of gas monitor cutoff instrument.
Adopt foregoing circuit, during the automatically controlled main transformer power-off of coal-winning machine, 12 volts power supplys of uninterrupted power supply output supply the cutoff instruments use, and cutoff instrument works on, and has realized the gas continuous monitoring.
Description of drawings
Fig. 1 is the structural representation of a kind of gas monitor cutoff instrument of the utility model control circuit.
Embodiment
Gas monitor cutoff instrument control circuit as shown in Figure 1; Comprise automatically controlled main transformer 1, gas monitor cutoff instrument 2; This circuit is provided with a charging accumulate formula power supply 3; The input of charging accumulate formula power supply 3 is connected an output of automatically controlled main transformer 1, and output is connected with gas monitor cutoff instrument 2 inputs, and another output of automatically controlled main transformer 1 is connected with the input of gas monitor cutoff instrument 2.
During practical implementation, gas automatically controlled main transformer 1 non-transformer of coal-winning machine that exceeds standard quits work, and at this moment, 12 volts power supplys of charging accumulate formula power supply 3 outputs supply 2 uses of gas monitor cutoff instruments, and gas monitor cutoff instrument 2 works on, and has realized the gas continuous monitoring.
