The front door of switch board 20 is carried out in debugging process, and the charging external equipment electrically connected with socket 24 occurs that charging can not be continued
During situation, if now illuminating lamp 251 is still lighted, have be due to as far as possible very much external equipment itself damage reason, if according to
Bright lamp 251 extinguishes, then be most likely due to and meanwhile protect socket 24 and lighting unit 25 the first breaker 26 detect it is slotting
The situation such as electric leakage or overload occurs for the circuit where seat 24 and lighting unit 25, and causes the first breaker 26 to disconnect electricity where it
Road is so as to protect the reason of socket 24 and lighting unit 25.If illuminating lamp 251 extinguishes, but socket 24 can still continue to set to external
Standby charging, then explanation is that illuminating lamp 251 is damaged.So as to pass through both illuminating lamps 251 in socket 24 and lighting unit 25
Between the exception that occurs, quickly and efficiently abnormal conditions are judged, the efficiency of breakdown judge, convenient work people is improved
Member carries out scene investigation with solving failure problems.
The side plate of cabinet 21 is blocked on side plate outer surface by opening provided with an opening and sets air-conditioning 23.The electricity of air-conditioning 23
The fire wire output end electrical connection that source input is electrically connected with the first hole in disconnecting switch 22 with socket 24, the power supply of air-conditioning 23 is defeated
Go out end to electrically connect with the zero line output end of disconnecting switch 22, the ground protection line end of air-conditioning 23 and the ground protection of disconnecting switch 22
Line output terminal is electrically connected.The top plate inner surface of cabinet 21 be provided with the second door limit switch, the Enable Pin of air-conditioning 23 with second
Limit switch is electrically connected in series.The effect of second door limit switch is realized when front door is closed, and air-conditioning 23 opens work, right
Because the thermal losses that the work of all components is produced carries out radiating treatment in PLC control cabinet 20 so that warm in the cabinet of PLC control cabinet 20
Degree is kept within the specific limits, the average most senior engineer that mean temperature can be born in most of component in control PLC switch board 20
Make 45~50 DEG C of temperature；When front door is opened, air-conditioning 23 is stopped, and no longer to being radiated in cabinet, is beaten using front door
Heat and the logical radiating of cabinet outer air flow in rear cabinet are opened, the effect of energy-conserving and environment-protective is reached.The mainboard of the cabinet 21 of PLC control cabinet 20 is led
Rail is provided with the first hole electricity with socket 24 in the second breaker 27, the live wire input and disconnecting switch 22 of the second breaker 27
The zero line output end electrical connection of the fire wire output end electrical connection of connection, the zero line output end of the second breaker 27 and disconnecting switch 22；
The power input electrical connection of the fire wire output end of second breaker 27 and air-conditioning 23, two line output terminals of the second breaker 27 with
The zero line output end electrical connection of disconnecting switch 22.Air-conditioning 23 is electrically connected in series with the second breaker 27.
By will be electrically connected in series after socket 24 and the electrical connection in parallel of lighting unit 25 with the first breaker 26, first is realized
Breaker 26 is protected to occurring to protect while the situation such as electric leakage or overload in two parallel circuits of socket 24 and lighting unit 25
Effect of the computer and illuminating lamp 252 of the staff of field adjustable from damage.The series electrical of 23 and second breaker of air-conditioning 27
Electrically connected respectively with the first breaker 26, socket 24 and the parallel connection of lighting unit 25 after connection.
Car body welding producing line of the present utility model is with PLC control cabinet operation principle：
Car body welding producing line of the present utility model PLC control cabinet 20, is set by the front door outer surface in cabinet 21
There is socket 24 to provide 220V working powers there is provided the external equipment being electrically connected.It is electric between socket 24 and disconnecting switch 22
Connect the first breaker 26.Be provided with lighting unit 25 in cabinet 21 simultaneously, lighting unit 25 with socket 24 is in parallel electrically connect after and
First breaker 26 is electrically connected in series, and the first breaker 26 protects socket 24 and lighting unit 25 from being leaked electricity due to circuit simultaneously
Or overload etc. caused by damage.When opening the front door, illuminating lamp 251 is lighted, when closing the front door, illuminating lamp
251 extinguish, and play and carry out the internal debugging of PLC control cabinet 20 offer illuminating effect to live cabinet commissioning staff.Controlled when opening PLC
When front door described in cabinet 20 processed is debugged, the situation that can not continue charging occurs for the charging external equipment electrically connected with socket 24
When, if now illuminating lamp 251 is still lighted, have be due to as far as possible very much external equipment itself damage reason, if illuminating lamp
251 extinguish, then are most likely due to while protecting the first breaker 26 of socket 24 and lighting unit 25 to detect socket 24
Occur the situation such as electric leakage or overload with the circuit where lighting unit 25, and cause the first breaker 26 disconnect it where circuit from
And protect the reason of socket 24 and lighting unit 25.If illuminating lamp 251 extinguishes, but socket 24 can still continue to fill to external equipment
Electricity, then explanation is that illuminating lamp 251 is damaged.So as to by the illuminating lamp 251 in socket 24 and lighting unit 25 between the two
Abnormal conditions are quickly and efficiently judged by the exception of appearance, are improved the efficiency of breakdown judge, are facilitated staff to enter
Row scene investigation is with solving failure problems.Air-conditioning 23 is arranged with the side plate with opening of cabinet 21, by making for air-conditioning 23
Energy end is electrically connected in series with second door limit switch, is realized by the second door limit switch when the front door of cabinet 21 is closed
When, air-conditioning 23 opens work, interior to PLC control cabinet 20 because the thermal losses produced when all components work is carried out at radiating
Reason.When the front door of cabinet 21 is opened, air-conditioning 23 is stopped, no longer to being radiated in cabinet, so as to reach energy-conserving and environment-protective
Effect.The air-conditioning uses the air-conditioning with condenser/evaporator, and air in PLC control cabinet 20 is carried out by condenser/evaporator
Condensation and vaporization cycle alternate treatment, reach the problem of radiating in cabinet and solve common air-conditioning leak, it is ensured that the drying of cabinet
And safety, so as to greatly enhance the practicality of PLC control cabinet 20.
