Abstract
The utility model discloses a main fan air electric lock automatic control device. The device comprises a main fan power supply loop and an underground power supply loop, wherein a circuit mutual inductor (B) is arranged on any single phase of the main fan power supply loop; an underground power supply control switch (4) is connected with the underground power supply loop in series; a normally open contact of a current relay (J) is connected with the underground power supply control switch (4); and the current relay (J) is positioned between the circuit sensor (B) and the normally open contact of the current relay. According to the device, the underground power supply loop is completely isolated from the main fan power supply loop; the safety performance of a circuit is improved; and the device has the advantages of simple circuit design, reliable working performance and high practicability.
Description
Technical field
The utility model relates to a kind of mine ventilation control gear, relates in particular to a kind of main pectinid electric locking automatic controller.
Background technique
Fan stoppage breaker is mine safety installations commonly used, cuts off the working power of down-hole when the fan stall,, causes the harmful gas concentration such as gas to be above standard and causes security incident because mine ventilation is bad to avoid.
The whole ventilation system in down-hole is comprised of the fan that size and quantity do not wait, and they are distributed on each position in mine, bears the task of down-hole air-supply.Be divided into two kinds of main fan and portable blowers according to the size of effect, the air output of down-hole depends primarily on fan.All fans and underground work electricity consumption are supplied with by central substation, and each fan place all send electricity to the down-hole.
Existing fan stoppage breaker mostly adopts on the spot lock between air and electricity mode, namely when the fan stall in colliery, cuts off on the spot underground power supply used.It goes a little is can't cut off a distant place underground power supply used, also just scolds when the fan blowing-out, can't realize that omnibearing down-hole cuts electricity.Therefore, still there is the possibility of gas explosion in the down-hole.In order to address the above problem, method commonly used is that local landscape electric substation sends warning behind the signal of receiving the fan stall, by the center dispatcher in the long-range central substation of staff's Advise By Wire on duty, then manually cuts off total power supply.This mode easily produce careless omission, and reaction velocity is relatively slow, can't guarantee the safety of down-hole owing to all adopting manual control.
Summary of the invention
The utility model has overcome the deficiencies in the prior art, and a kind of main pectinid electric locking automatic controller is provided, and is intended to stop the security incident that causes because of the fan stall.
The technical solution adopted in the utility model is: a kind of main pectinid electric locking automatic controller, comprise main fan current supply circuit and well dynamic current supply circuit, described main fan current supply circuit comprises the power supply 1 of main fan, current transformer B, main fan 2, described current transformer B be installed in described main fan current supply circuit arbitrarily single-phase on, described well dynamic current supply circuit comprises well dynamic power supply 3, well dynamic power control switch 4, well dynamic load 5, described well dynamic power control switch 4 is connected on the well dynamic current supply circuit, the normally opened contact of current relay J links to each other with described well dynamic control switch 4, and current relay J is between current transformer B and current relay normally opened contact.
The beneficial effects of the utility model are: well dynamic power supply circuits and main fan power supply circuits are isolated fully, have improved the Safety performance of circuit; It is simple that the utility model has circuit design simultaneously, reliable working performance, the advantage such as practical.
Description of drawings
Fig. 1 is circuit diagram of the present utility model.
1 power supply 2 for main fan is that current transformer J be current relay for well dynamic power control switch 5 for well dynamic load B for well dynamic power supply 4 for main fan 3.
Embodiment
The utility model is described in further detail below in conjunction with accompanying drawing:
As shown in Figure 1, a kind of main pectinid electric locking automatic controller, comprise main fan current supply circuit and well dynamic current supply circuit, described main fan current supply circuit comprises the power supply 1 of main fan, current transformer B, main fan 2, described current transformer B be installed in described main fan current supply circuit arbitrarily single-phase on, described well dynamic current supply circuit comprises well dynamic power supply 3, well dynamic power control switch 4, well dynamic load 5, described well dynamic power control switch 4 is connected on the well dynamic current supply circuit, the normally opened contact of current relay J links to each other with described well dynamic control switch 4, and current relay J is between current transformer B and current relay normally opened contact.
Shown in Fig. 1, working principle of the present utility model is as follows:
The electric current of current transformer B monitoring is that the power supply 1 of main fan is to the monophase current of main fan 2, the electric current of monitoring is input to the current coil of current relay J, the switch output contact of current relay J is normally open, the switch output quantity is input to well dynamic power control switch 4, is serially connected in the secondary circuit of underground power supply used control switch 4.
When main fan 2 normal operation, the current value of a definite value of current transformer B output, the closed conducting of output switch of this current value control current relay J, switching value to a closed conducting of well dynamic power control switch 4 inputs, well dynamic power control switch 4 can normally stop to send the electricity operation, when main fan 2 is out of service, current transformer B does not have current value output, the output switch of current relay J disconnects, switching value to a disconnection of well dynamic power control switch 4 inputs, because the output switch of current relay J is serially connected in the secondary circuit of well dynamic power switch 4, thereby control well dynamic power switch 4 disconnects rapidly, can not again send electricity, thereby realize the effect of lock between air and electricity.
