Description
Technical field
The utility model belongs to electric equipment field, is specifically related to a kind of DC power system of high-tension switch cabinet.
Background technology
The Main Function of switch cubicle (switchgear) is in the process of the generating of electric power system, transmission of electricity, distribution and electric energy conversion; carry out folding, control and protection power consumption equipment, it is applicable to the various different occasions such as power plant, transformer station, industrial enterprise and residential quarters.In switch cubicle, be typically provided with circuit breaker (or isolating switch or on-load switch), operating mechanism, instrument transformer and various protective devices etc.At present, have for the sorting technique of switch cubicle a variety of, as being divided into withdraw-type switch cabinet and fixed switching cabinet by circuit breaker mounting means; According to the difference of cabinet body structure, can be divided into metal closed switch cabinet and metal enclosed armoured switch cabinet; Can be divided into again high-tension switch cabinet, Medium Voltage Switchgear and low-tension switch cabinet etc. according to electric pressure difference.
Wherein, above-mentioned high-tension switch cabinet because of the electric pressure of its conveying high, transmission power is large, therefore be widely used in the larger part of electric load.Along with economical and scientific and technological fast development, more and more higher to the requirement of power supply reliability.Although existing high-voltage switch gear is provided with circuit breaker (or isolating switch or on-load switch), operating mechanism, instrument transformer and various protective devices etc. cashier's office in a shop; but when after a certain major loop power-off; above-mentioned circuit breaker (or isolating switch or on-load switch), operating mechanism and various protective device also may have a power failure thereupon; and then forfeiture protective effect, now just cause huge potential safety hazard to electric power system.So; in order to make high-voltage switch gear protective device cashier's office in a shop can continue reliability service; the also supporting DC power system that is provided with high-tension switch cabinet, and be adopted as circuit breaker, operating mechanism and various protective devices etc. DC power supply is provided, thus further guarantee the reliability of power supply.
The DC power system of the high-tension switch cabinet of prior art includes circuit module, fills feed cabinet, batteries for what circuit module was set, and for laying the battery cabinet of batteries, described in fill feed cabinet and described battery cabinet for being arranged side by side.Circuit module is wherein mainly by high frequency power module, alternating current-direct current monitoring unit, the total monitoring module of system, pressure unit module, battery inspection module, the compositions such as insulating monitoring.But the DC power system of the high-tension switch cabinet of prior art has following weak point (referring to accompanying drawing 1):
1, the control electric power loop switch 3 filling in prior art on feed cabinet 1 exposes, and then has the situation of by mistake being touched, and has certain potential safety hazard.
When the main power supply loop power-off of circuit breaker, operating mechanism and the various protective devices that 2, open the light cashier's office in a shop when each high pressure, come rapidly to its power supply, because instantaneous load is larger, therefore will cause a large amount of heatings of batteries by batteries.But the radiating effect of storage battery cabinet of the prior art is poor, cause the overheated operation of storage battery, accelerate the aging of storage battery, and then be unfavorable for the long-term stability operation of batteries.
3, existing employing feed cabinet 1 and battery cabinet 2 adopt natural draft simultaneously, and be provided with ventilation grid 4 in the lower end of the front panel of feed cabinet 1 and battery cabinet 2, flow in cabinet for air, and flow out from the venthole at two cabinet tops, but so, because this direct current system has staff frequently, it is maked an inspection tour, staff is in the close process of this direct current system, the dust of kicking up while understanding walking is brought in cabinet from ventilation grid 4, increase the weight of the accumulation of dust in cabinet, again because dust has insulation and corrosivity, and then may easily cause electric contact loose contact, the reliability of impact power supply.
To sum up, applicant considers to design one and can be touched by prevention and control electric power loop switch by mistake, the DC power system of storage battery cabinet better heat-radiation effect and the better high-tension switch cabinet of dust-proof effect.
