The main contactor monitors the phase failure, power failure, under-voltage and over-voltage of the power supply, and the small relay monitors whether the fan coil is electrified or not, so that the minimum ventilation in the pig house is ensured.

The principles of operation in this embodiment are described in detail below with reference to the drawings to provide a person skilled in the art with a better understanding of the present utility model:

As shown in fig. 1-8, assuming a total of 16 pig house fan power boxes, the sub-box total contactors correspond to km1..km 16, the sub-box mini-relays correspond to KA 1..ka 16, the toggle switch and the sub-box indicator lamps are respectively corresponding to numbers 1-16 (omitted in the schematic diagram, the connection modes of the 16 indicator lamps are the same), and the power indicator lamp and the corresponding toggle switch are marked as 17.

Then assume 1: under normal use condition, the 17 # toggle switch is in an on state, the contactor KM works, two pairs of NC contacts are not connected, the entrance guard power supply is powered by mains supply, and the storage battery is always kept in a charging state by the entrance guard power supply module. When the breaker QF in the alarm box trips or 220V power is not supplied to the breaker QF, the access control power module is powered by a storage battery, the contactor is not operated at the moment, a signal is transmitted to the NC end of the contactor KM from the GND point of the power module, and then transmitted to PUSH from the other NC end of the contactor KM, at the moment, the NO point of the access control power module has +12VDC output, a +12VDC voltage signal is transmitted to an indicator lamp and an audible and visual alarm through the NC contact of the contactor KM and a 17-number toggle switch, at the moment, the indicator lamp is on, the audible and visual alarm works, and when nearby workers see or the channel audible and visual alarm is flashing or sound, the 17-number indicator lamp is on through checking, the alarm box power failure can be judged.

Suppose 2: the fan power box of the farrowing house 2 is correspondingly numbered No. 2 (called No. 2 electric box for short), then the corresponding sub-box total contactor is KM2, the sub-box miniature relay is KA2, the sub-box phase sequence protector is JVR2, and the toggle switch and the sub-box indicator lamp are both No. 2. When the three-phase power supply normally works, the toggle switch is in an on state, the main sub-box contactor KM2 is in a working state, the three-phase power supply can normally pass through the sub-box contactor KM2, the small sub-box contactor is in a working state, and at the moment, the indicator lamp is not on, and the sub-box alarm B does not work.

1. When the monitored 24 inch or 36 inch fan motor is damaged, the contactor KM (24 inch or 36 inch) burns OUT or other conditions cause that a 220VAC power supply is not connected to the lower end of the contactor KM (24 inch or 36 inch), KA2 stops working, the normally closed NC point of KA2 is connected, GND signals are fed back to the PUSH point through the green signal line through the NC point of KA2, the NO point of the access control power supply module outputs +12VDC voltage, the signal output alarm box is transmitted to the other group NC point of KA2 through the yellow signal line and then is transmitted to the 2 # toggle switch through the blue signal line, the +12VDC signals reach the 2 # indicating lamp and the relay module, the 2 # indicating lamp is on, the relay module works simultaneously, the +12VDC signals are transmitted to the yellow-green double-color signal line at the moment, 12VDC voltages are arranged between the yellow-green double-color signal line and the black signal line, the power supply of the sub-box alarm B (the quantity of the installation alarm can be determined according to the size of a pigsty) is connected with the yellow-double-color and black signal line, and the alarm is powered. When the person hears the alarm sound to the alarm box (comprising the alarm sub-box and the alarm main box) to check that the indicator lamp is the number 2 sub-box indicator lamp, the fault of the number 2 electric box (the alarm sub-box) can be judged.

2. When the three-phase power supply of the No. 2 electric box lacks phase, the contact of the phase sequence protector JVR is disconnected, KM2 stops working, KA2 stops working, normally closed NC points of KM2 and KA2 are connected, GND signals are fed back to PUSH points through green signal lines through NC points of KM2 and KA2, at the moment, the NO point of the access control power supply module outputs +12VDC voltage, the signal output alarm box is transmitted to the other group NC points of KM2 and KA2 through yellow signal lines and then is transmitted to a No. 2 toggle switch through blue signal lines, the +12VDC signals reach the No. 2 indicator lamp and the relay module, at the moment, the No. 2 indicator lamp is on, meanwhile, the relay module works as a second relay, the +12VDC signals are transmitted to a yellow-green double-color signal line, at the moment, 12VDC voltages are arranged between the yellow-green double-color signal lines, and the alarm B (the quantity of the installed alarm can be determined according to the size of a pigsty) power supply is connected with the yellow-green-color signal line, at the moment, the alarm is powered up, and the alarm is powered. When the personnel hear the alarm sound and the alarm box look over and find that the indicator lamp is on No. 2, then the fault of the No. 2 alarm sub-box can be judged.

And if the No. 2 electric box has no power supply, referring to the phase failure condition.

In summary, the utility model is provided with the plurality of alarm sub-boxes, the alarm sub-boxes are correspondingly provided with the indicator lamps, each indicator lamp corresponds to one pigsty, and people can quickly know which pigsty to alarm by checking when in alarm, so that faults are convenient to process in time; the alarm horn is a high-decibel low-voltage direct-current horn, can be uniformly arranged in various areas such as a corridor and a rest area, and is connected in parallel; thirdly, a 24 inch (or 36 inch) fan is added for monitoring, the fan is required to be manually normally opened, if other fans do not work in winter when the weather is cold, only one fan is started to keep the minimum ventilation quantity, so that the monitoring of the fan is very important, and the dangerous situation that one fan does not work can be prevented; and fourthly, the power supply can be disconnected in time when the power supply is in phase failure, power failure, under-voltage and overvoltage, and an alarm is given to protect equipment, so that the equipment is prevented from being damaged due to abnormal power supply, and the problem of the background technology is solved.
