Background technique
With the development of power electronics technology, electronic circuit component has more and more applied to electric control system of petroleum
In, since variation sensibility of the electronic circuit component to temperature is higher, when electric control system for drilling machine is when low temperature environment comes into operation, due to
The reason of temperature, can seriously affect the normal operation of equipment, especially in low temperature environment, as frequency converter (0 DEG C or less) can not open
It is dynamic, air-conditioning (- 10 DEG C or less) is unable to run etc., if electrical component is allowing forced service outside temperature range, component wear
A possibility that it is very big.
Environment temperature there may be the problem of have: 1. pairs of electric-control system electric elements insides, for example, control touch screen, micro- electricity
Road plate, (PCC) power, IGBT etc., the requirement to ambient temperature and humidity is more sensitive, if being powered outside range of operation will lead to device
Part is damaged or is not worked, therefore is both needed to setting temperature-humidity detecting device in critical positions.
2. the air-conditioning system of pair automatically controlled configuration, the normal operating temperature lower limit that can bear under normal circumstances about at -10 DEG C,
When low temperature environment, if directly use will lead to machine inside and outside air-conditioning, there is operation irregularity or shuts down phenomenon in especially control loop,
If forced service but will damage air-conditioning system, therefore need to carry out technology change to air-conditioning system.
Summary of the invention
The purpose of the present invention is in addition to control room in existing air conditioner refrigerating, hot environment trouble-free operation other than, in low temperature
Also to guarantee electric control system for drilling machine reliability service under state, it is ensured that stable operation of the electric-control system under round-the-clock environment temperature,
The method for proposing electric control system for drilling machine reliability service in low temperature environment.
Technical solution of the present invention: a kind of method of electric control system for drilling machine reliability service in low temperature environment, drilling machine are automatically controlled
System, which controls, is equipped with air-conditioning in room, with air conditioner refrigerating, which has outdoor unit, indoor unit, and outdoor unit is connected to gas with indoor unit
Pressure pipeline, setting dehumidifying and heater in electric control system for drilling machine control room are automatic when temperature and humidity is more than setting threshold values in room
Starting operation, it is ensured that the temperature in control room is within the scope of equipment safety operation；
The heater with function of temperature control is added in outdoor machine of air-conditioner position；Automatically controlled shutter is installed additional in outer machine heat radiation air outlet upper end
Formula exhaust fan, reload temperature control device at outdoor machine of air-conditioner, temperature signal access venetian blind type exhaust fan power control loop, temperature
Spend control device and venetian blind type exhaust fan linkage control；Install pressure detecting dress additional on the air pressure pipeline of connection outdoor machine of air-conditioner
It sets, and the pressure detecting signal measured is accessed into outer machine fan control circuit, pressure-detecting device and outer machine fan linkage control；
Control process: when electric-control system comes into operation under lower than -10 DEG C environment, system meeting automatic alarm prompt, which simultaneously actively starts, to be controlled
In room processed and the heater of outdoor machine of air-conditioner position is alarmed when rising to safe threshold or more with outdoor machine of air-conditioner temperature in control room
It automatically terminates and operator's electric-control system is prompted to be in standby starting state；During electric-control system is run, when temperature is super in room
After crossing setting value, air-conditioning puts into operation, compressor operation, since outdoor machine of air-conditioner is in external environment, the temperature rise that heater generates
It is relatively slow, to avoid air conditioner low temperature from protecting, air conditioner refrigerating work is influenced, outer machine heat radiation air outlet upper end venetian blind type exhaust fan is in
Closed state；
Compressor operation rises the air pressure line pressure for being connected to outdoor unit and indoor unit, and pressure-detecting device detects pneumatic tube
The pressure of line, when pressure reaches setting value, outer machine fan brings into operation；Outer machine temperature is more than venetian blind type row after setting value
The shutter of fan is opened, and the heat of outdoor machine of air-conditioner accumulation is discharged.
Further, the pressure of the temperature signal of heter temperature signal, temperature control equipment, pressure-detecting device is believed
Electric-control system main logic number is accessed, and is monitored in real time in HMI and Industrial PC.
The beneficial effects of the present invention are: ensuring that electric control system for drilling machine in the normal operation of low temperature state, and is reequiped
Required material is easy to get, is easy for assembly；
The purpose of indoor setting heater is since electrical equipment is unable to run in low temperature environment, and increasing heater makes running environment
Temperature rises, and meets service condition；
Outdoor machine of air-conditioner position is placed heater purpose and is heated for compressor, because compressor of air conditioner has minimum operating temperature, if
Compressor is run lower than this temperature, compressor can be damaged；
Pressure-detecting device is that protection compressor can work within the scope of pressure limits, if superpressure, air-conditioning system can report event
Barrier is shut down；
Exhaust fan is the heat exchange for controlling outdoor machine of air-conditioner and external environment, it is ensured that outer machine operating ambient temperature can run model
In enclosing.
