Description
Technical field
The utility model relates to high-tension switch cabinet, particularly 10 kilovolts of feeder line intelligent switchboards.Be mainly used in the automatic control of railway 10 kilovolts of feeder lines along the line, or other 10 kilovolts of power circuits.
Background technology
Existing switch cubicle structure adopts the metal cabinet usually, and the turnover jockey is equipped with switching cycle and servicing unit and forms.Chinese patent literature 00217399 disclosed " the fixed indoor metal enclosed switchgear of box " is exactly to be made up of bus-bar room, switch gear room, cable vault, low voltage control chamber.Bus is arranged on the top of switchgear, and the middle part is the switch gear room, and the bottom is the cable vault, and the front portion is the low voltage control chamber; Chinese patent literature 00259892 disclosed " metal closed switch cabinet ", comprise cabinet, be arranged on the insulator of cabinet internal upper part, a main busbar and a busbar, the isolating switch that is arranged on upper back in the cabinet and is connected with a busbar output, be installed in vacuum circuit-breaker and man-operating mechanism in the cabinet by the vacuum circuit-breaker mounting panel, be installed in aluminium matter vertical clapboard in the cabinet by supporting bracket, be installed in the current transformer on the aluminium matter dividing plate, be installed in one group of supporting insulator on the supporting bracket; Chinese patent literature 01255174 disclosed " a kind of fixed indoor metal enclosed switchgear ", comprise interconnected cabinet and cabinet door, in cabinet, be provided with the bus-bar room that is positioned at rear portion on the cabinet of unique spacer and the breaker chamber at middle part, be provided with a handcart in the described breaker chamber, above-mentioned upper and lower isolating switch side respectively is contained in the cabinet door described in bus-bar room and the cable vault and comprises the upper, middle and lower door, wherein middle student's side and cabinet hinge joint, door is opened under last master in making.The switch cubicle of said structure and rationally is provided with their outside the mutual electrical connection of each device for switching that guarantee to constitute switch cubicle in cabinet, to guarantee the work safety of switch cubicle.According to the knowledge of the applicant: the switch cubicle of said structure all adopts conventional control device and device for switching combination, so automaticity is lower.In China, because the speed-raising of railroad train and the increase of rate of traffic flow, make railway 10 kilovolts of feeder line automatic block signal systems along the line improve thereupon, need the high-voltage intelligent switch cubicle of function admirable to replace existing high-voltage switch gear case the requirement of power supply reliability.And the situation of reality is, railway 10 kilovolts of electric power of relating to of automatically closing up along the line connect that circuit is long, and the circuit corridor is with a varied topography, and common operating condition is poor, therefore, guarantee 10 kilovolts automatically close up, the safe operation of electric power through track just seems more and more important., through track reliability service self-closing in order to guarantee, common solution be, by two adjacent, use the distribution substations of double-cricuit supply power supply to feed out in opposite directions, and in the minizone with isolating switch with line sectionalizing, make it to form looped network.When a certain minizone supply line fault, the isolating switch at faulty line two ends separately, the excision faulty line is restored electricity by another supply arm.But this operational mode by the manually operated circuit block switch can not satisfy the requirement that train speed raising and rate of traffic flow increase, and general measure now is to come sectionalized line by the switchgear at the dispatching terminal remote operation.When the line fault of minizone, the switchgear at dispatch terminal telemechanical disjunction faulty line two ends, excision faulty line.This " telemechanical " automated system can only be by the repeatedly interoperation of each switch on the circuit, and interpretation " time difference ", " difference between current ", " number of times is poor " are waited and discern and isolated fault.Because 10 KV distribution nets of China adopt isolated neutral or small current neutral grounding mode more, single-phase-to-ground current is less, thereby said system can only discern phase fault, for single phase ground fault, has then that identification error is big, the long weak point that maybe can not discern of recognition time.
