Description
Technical field
Based on indoor environment temperature intelligence control method of the electrical equipment of temperature gap and device thereof; Belong to the indoor environment temperature intelligent control technology of electric system and power consumer electrical equipment; Should guarantee the temperature environment that the electrical equipment safe operation is necessary, make electric energy loss be in floor level again.
Background technology
The electrical equipment of indoor use is because its conductor dbus excess current under the effect of self-resistance and connecting portion contact resistance, is understood produce power loss (coil class electrical equipment also can produce electromagnetic consumable under the effect of electromagnetic field); These energy losses all convert heat energy to; Make the temperature rising in various degree at each position of electrical equipment, it is the process of a vicious cycle that temperature raises, and can cause the running temperature of electrical equipment constantly to raise as not taking measures; Meet or exceed the running temperature limit value of permission; Influence equipment service efficiency and operation life, can insulate by damage equipment when serious, even cause electrical equipment to burn out; Cause power failure, therefore must equipment heating be controlled within certain scope." heating of GB763-1990 ac high-voltage electrical equipment when long-term work " just stipulated that the normal environment for use condition of electrical equipment ambient air temperature is not higher than 40 ℃; Recommend the every reduction of surrounding air environment temperature 1K; It is specified 0.5% that the electrical equipment load current can increase, but do not allow to surpass 20% of nominal load, when ambient air temperature surpasses 40 ℃ (but not being higher than 60 ℃); Every increase 1K should reduce current capacity 1.8%; Permission temperature rise when the highest permission running temperature and the ambient air temperature of also having stipulated dissimilar conductors, electric parts, insulating material etc. simultaneously surpasses 40 ℃.
The degree of heat of same electrical equipment and institute on-load size, indoor environment temperature, equipment healthy water equality factor are relevant, under the normal condition through guaranteeing that electrical equipment is operated in certain ambient temperature range, ensures the electrical equipment safe operation.The indoor environment temperature control of conventional electrical equipment generally is fan electromotor or the air-conditioning (following general designation refrigeratory) in the indoor installation some of electrical equipment; Adopting fan reinforcement indoor-outdoor air to flow dispels the heat; Utilize air conditioner refrigerating to guarantee indoor proper temperature environment in addition; Also have by the air Natural Circulation, modal is the fan radiating mode.Generally on the building wall of the hyperbaric chamber that electrical equipment is installed, switchgear building, electrical source of power chamber etc., install the fan electromotor of some additional, according to the operation of indoor temperature value control fan electromotor.The cooling device that installs additional all will consume certain electric energy, and its input and excision are divided into manual or automatic two kinds of patterns, and comparatively advanced is to drop into pattern automatically according to indoor environment temperature now.There is following shortcoming in present conventional radiating mode: 1, no matter electric equipment operation whether; When indoor temperature reaches setting valve; Will put in order group all forces cooling device to drop into; When the equipment shut down condition of causing need not dispel the heat, also drop into whole fan electromotors or air-conditioning, caused waste of energy.2, when electrical equipment generation firing accident, indoor environment temperature is bound to, and (under the refrigeratory normal operating condition, the indoor temperature of electrical equipment does not generally allow to be higher than 60 ℃ to high extremely temperature actuated definite value; If temperature is higher than this value far away; Can judge that abnormal accident has taken place electrical equipment), cooling device still remains on operation or is activated state, and air flow forces to accelerate; The development of meeting expansion or aggravation accident is unfavorable for catching fire and puts out.3, when electric equipment operation, though the heating level of equipment own is not high, when indoor environment temperature was higher, under the condition that satisfies the requirement of electric equipment operation environment temperature, cooling device was forced and puts into operation, has also caused the unnecessary too much loss of electric energy.When 4, the outside atmosphere environment temperature is low; Though indoor environment temperature does not reach the startup definite value as yet sometimes, the heating level of electrical equipment self is very high, consumes a large amount of electric energy; Just need further to reduce the equipment heating level through heat radiation; And the cooling device of this moment often can not in time put into operation, causes the hot(test)-spot temperature of operation electrical equipment too high, influences its safe operation; The power of electrical equipment autophage also tends to surpass the power consumption of the cooling device that drops into, and is extremely unreasonable economically.
