Description

Integrated environment regulation and control device and environment regulation and control method
Technical Field
The invention belongs to the technical field of power transformation ventilation equipment, and particularly relates to an integrated environment regulation and control device and an environment regulation and control method.
Background
With the development and popularization of computers, the number of computer systems is increasing day by day, the number of matched environment equipment is also increasing day by day, and an intelligent power distribution room becomes a trend. The equipment of the power distribution room must provide a normal electricity utilization environment for the user at all times. Once the equipment is out of order, the electricity consumption of the user can be influenced, the normal work and life of enterprises, public institutions and families are threatened, if the accident is serious and cannot be handled in time, the hard equipment can be damaged, and serious consequences are caused.
At present, the power distribution network is increasingly large, and the pressure of a plurality of power distribution rooms for managing power maintenance departments is increased day by day. Because most distribution rooms are unattended, the customers inform the operation and maintenance department to process the power failure only after the power failure occurs. The method has the problems of slow reaction and unclear field condition and low treatment efficiency.
Currently, for power distribution rooms in the power, water conservancy, railway, chemical industry, petrochemical industry and the like, there are roughly the following common environmental situations:
1. the humidity is large throughout the year-the probability of condensation and partial discharge is increased; particularly, in the alternative of spring summer and autumn, the climate characteristic of 'moisture regain', namely 'condensation phenomenon', is very easy to appear;
condensation is very harmful to electrical equipment:
(1) dew formed on a secondary wiring terminal row in a terminal box mechanism box corrodes a metal conductive part on the terminal row, alternating current and direct current short circuit grounding is easily caused after the metal conductive part is corroded seriously or other impurities such as dust are mixed in the metal conductive part, direct current grounding causes great harm to stable operation of a secondary system of a transformer substation, practical operation experience shows that direct current grounding is mostly caused by water attached to a charged part, the dew even causes short circuit between two secondary wires on the terminal row more seriously, and if the dew is just a switch tripping circuit, misoperation of a switch can be immediately caused, and a power failure accident is caused.
(2) Dew that forms on switch or switch operating device can corrode the metal parts in the mechanism, influences the life of mechanism, causes the mechanism card puckery because of the corrosion even, leads to switch or switch to construct and can not move in place when deciliter, if consequently make switch sound contact divide slowly and close slowly, then can cause very big electric power accident, especially the switch corrosion phenomenon can be more serious when not operating for a long time.
(3) Generally, the high-voltage chamber is more concerned with ventilation, so the indoor temperature and humidity are greatly influenced by the outdoor environment, condensation is easily generated in the indoor high-voltage switch cabinet, the waterproof performance of an insulating porcelain bottle in the cabinet is not considered, the insulativity of the insulating porcelain bottle can be reduced if dew exists on the insulating porcelain bottle, the creepage or flashover phenomenon can be caused even, the normal operation of equipment is seriously influenced, particularly, some equipment is in a shutdown state, the internal temperature of the equipment is lower, condensation is more easily formed on the surface of the equipment, and at the moment, accidents are very easily caused once the power is transmitted.
2. The indoor temperature and humidity are high;
the electrical equipment is easily damaged by humidity in the use process, for example, the electronic components of the control equipment can cause faults if the electrical equipment is used for too long time in a high-humidity environment.
3. The situation of large-area indoor dust accumulation is serious;
the generation of dust not only pollutes the environment and damages the health of people, but also brings great harm to the safe operation of electrical equipment.
(1) The dust is agglutinated and settled around the electrical equipment, thereby reducing the electrical distance, destroying the insulation strength of the electrical equipment, and easily causing electrical breakdown short circuit accidents in the process of overvoltage of a line or electrical operation.
(2) The electric switch has poor contact, dust is accumulated between contacts of the electric switch and between electromagnetic cores, the electric switch has poor contact faults, and the electric switch has the greatest influence particularly in a relay-contactor control circuit. The electric control system is unstable in action and good and bad in time, so that equipment accidents are frequently caused by the phenomena of adhesion of single-phase operation contacts and the like.
4. Indoor toxic gas accumulation;
affecting the physical and mental health of operation and maintenance personnel.
Some situations exist above, all bring certain potential safety hazards to the normal operation of equipment.
