Integrated environment regulation and control method

Abstract

The invention discloses an integrated environment regulation and control method, and belongs to the technical field of substation ventilation methods. An integrated environment regulation and control device is adopted. The method comprises the following steps that 1, when (T-T<outdoor>) is larger than or equal to T<first set value>, and RH<outdoor> is smaller than or equal to RH<first set value>, a fresh air passage is opened; 2, when (T-T<outdoor>) is larger than or equal to T<first set value>, and RH<outdoor> is larger than RH<first set value>, fresh air outside a power distribution room is dehumidified through the fresh air passage; and 3, when (T-T<outdoor>) is smaller than T<first set value>, T is larger than or equal to T, or RH is larger than RH, an indoor air return passage is opened. According to the scheme that the indoor temperature is reduced by replacing air, the working power required by equipment is greatly reduced, and the advantages of energy conservation and high efficiency are achieved.

Description

[0001] This application is a divisional application with the application number 202011099482.2, the application date of October 14, 2020, and the title of the invention "integrated environmental control device and environmental control method". technical field [0002] The invention belongs to the technical field of power-changing ventilation methods, and in particular relates to an integrated environment control method. Background technique [0003] With the development and popularization of computers, the number of computer systems is increasing day by day, and the supporting environmental equipment is also increasing. Intelligent power distribution rooms have become a trend. The equipment in the power distribution room must provide users with a normal power consumption environment at all times. Once the equipment fails, it will affect the electricity consumption of users, and pose a threat to the normal work and life of enterprises, institutions, and families. If the acci...

Problems solved by technology

[0008] (1) The dew formed on the secondary terminal block in the terminal box mechanism box will corrode the metal conductive parts on the terminal block. If the corrosion is heavy or mixed with other impurities such as dust, it will easily cause AC and DC short circuit grounding, and DC grounding will affect the substation. The stable operation of the secondary system has caused great harm. Actual operating experience shows that the DC grounding is mostly caused by water adhering to the live parts, and what is more serious is that the dew even causes a short circuit between the two secondary lines on the terminal block. If it happens to be the switch trip circuit, it will immediately cause the switch to malfunction and cause a power outage.

[0009] (2) The dew formed on the switch or knife switch operating mechanism will corrode the metal parts in the mechanism, affect the service life of the mechanism, and even cause the mechanism to jam due to corrosion, resulting in the mechanism not operating in place when the switch or knife switch is opened and closed , if the moving and static contacts of the switch are opened and closed slowly, it will cause a huge electrical accident, especially when the switch has not been operated for a long time, the corrosion phenomenon will be more serious

[0010] (3) The high-voltage room generally pays more attention to ventilation, so the indoor temperature and humidity are greatly affected by the outdoor environment. Condensation is also prone to occur in the indoor high-voltage switch cabinet, and the insulating porcelain bottles in the cabinet are mostly not considered waterproof. If there is dew on it, it will Reduce its insulation, and may even cause creepage or flashover, which seriously affects the normal operation of the equipment, especially when some equipment is out of service, its internal temperature is lower, and it is easier to form condensation on its surface. prone to accidents

[0011] 2. High indoor temperature and humidity;

[0012] Electrical equipment is vulnerable to humidity during use. If it is used for a long time in a high humidity environment, the electronic components of the control equipment will cause failure.

[0013] 3. A large area of ​​indoor dust accumulation is serious;

[0014] The generation of dust not only pollutes the environment, damages people's health, but also brings great harm to the safe operation of electrical equipment.

[0015] (1) Dust condenses and settles around the electrical equipment, thereby reducing the electrical distance, destroying the insulation strength of the electrical equipment, and easily causing electrical breakdown and short circuit accidents during line overvoltage or electrical operation

[0016] (2) Poor contact of the electrical switch is caused. Dust accumulation between the contacts of the electrical switch and between the electromagnet cores will cause poor contact of the electrical switch, especially in the control circuit of the relay contactor.

The action of the electrical control system is unstable, sometimes good and sometimes bad, and the phenomenon of single-phase operation contact adhesion and other phenomena often cause equipment accidents

[0017] 4. Indoor toxic gas accumulation;

[0018] Affect the physical and mental health of operation and maintenance personnel

[0019] Some of the above situations will bring certain safety hazards to the normal operation of the equipment.
