Abstract
The utility model discloses a power distribution system and belongs to a prefabricated box-type transformer station of a 10kV system, which is simple in structure, high in cost performance and high in safety factor. According to the adopted technical scheme for solving the technical problem, the power distribution system comprises a switch cabinet and a metering box, wherein the switch cabinet is divided into three cavity rooms, the upper cavity room is a wire incoming switch cabinet, the middle cavity room is a transformer switch cabinet, the lower cavity room is a wire outgoing switch cabinet, the wire incoming switch cabinet is internally provided with a load switch, the high-voltage current input bus and the high-voltage current output bus of the switch cabinet are connected via the load switch, a fuse and a grounding switch are arranged on the load switch, and the load switch is arranged reversely in the circuit. The basic size of the prefabricated box-type transformer station is correspondingly reduced, the construction land is saved as the switch cabinets are reduced, the production cost is directly reduced, and product competitiveness and complete scheme solution ability are enhanced.
Description
Technical field
A kind of distribution system of the utility model, belongs to the prepackage type box-type substation of 10kV system.
Background technology
Pre-mounted box type transformer substation is little with its floor space, easy for installation, the advantages such as good looking appearance, power transmission and distribution terminal as residential quarters, be used widely, in 10 kilovolts of high-pressure sides of pre-mounted box type transformer substation, conventionally adopt one 10 kilovolts incoming line switch cabinet+mono-metering cabinet+mono-outgoing line cabinet, form a complete primary distribution system.The switch not with ground of the on-load switch in incoming line switch cabinet wherein, wire leading method is inlet wire under cable; On-load switch band fuse and the earthed switch of outlet switch cabinet, need to configure each of the wide incoming line cabinet of 650mm cabinet and outgoing line cabinet, one of the wide metering cabinet of 800mm cabinet.The profile of the pre-mounted box type transformer substation of this configuration mode also will strengthen, and causes cost to rise.How basic with the phase transformation of trying one's best few floor space and trying one's best little, meet the power transmission and distribution requirement of community, become a difficult problem for test enterprise primary system solution ability.
Utility model content
The purpose of this utility model is for providing a kind of features simple structure, and cost performance is high, the box-type substation of the 10kV that coefficient of safety is high.
In order to solve the problems of the technologies described above, the technical solution adopted in the utility model is: a kind of distribution system, comprise switch cubicle and metering cabinet, described switch cubicle is divided into three chambers, described upper chamber is incoming line switch cabinet, middle chamber is transformer switch cabinet, lower chambers is outlet switch cabinet, in described incoming line switch cabinet, be provided with on-load switch, the height of described switch cubicle is compressed between goddess of lightning's line and high pressure power outlet mother wire and is connected by on-load switch, on described on-load switch, be provided with fuse and earthed switch, described on-load switch upside-down mounting in the line, described metering cabinet is the electric power meter of distribution system.
Wherein, described service entrance switch is provided with switch gate cashier's office in a shop, is provided with middle switch gate on transformer, and outlet switch is provided with lower switch gate cashier's office in a shop.
Wherein, on described lower switch gate, be provided with band electromagnetic lock.
Wherein, the outlet method of described metering cabinet is outlet under cable.
The utility model compared with prior art has following beneficial effect: the utility model is by the inspection earthing function of the fuse short-circuit protection function of the isolation features of incoming line switch cabinet and outlet switch cabinet and earthed switch; with a upside-down mounting on-load switch with fuse and earthed switch, realize; and Xiamen band electromagnetic lock, by the forced blocking of on-load switch incoming power end, prevents mistakenly entering charged chamber.The primary system that the utility model forms with two switch cubicles, three functions that switch cubicle configuration just can reach have been reached, directly save a switch cubicle, and the key dimension of corresponding minimizing pre-mounted box type transformer substation, capital construction land used has been saved in the minimizing of switch cubicle, directly reduce production cost, promoted the ability of product competitiveness and total solution.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, the utility model is described in more detail.
Fig. 1 is the electrical block diagram of incoming line switch cabinet of the present utility model.
Fig. 2 is the electrical block diagram of outlet switch cabinet of the present utility model.
Embodiment
By reference to the accompanying drawings the utility model is described in further detail now, the schematic diagram of accompanying drawing for simplifying, basic structure of the present utility model is only described in a schematic way, so it only shows the formation relevant with the utility model.
As shown in Figure 1-2, a kind of distribution system, comprise switch cubicle and metering cabinet, switch cubicle is divided into three chambers, upper chamber is incoming line switch cabinet, middle chamber is transformer switch cabinet, lower chambers is outlet switch cabinet, in incoming line switch cabinet, be provided with on-load switch QL11, the height of switch cubicle is compressed between goddess of lightning's line and high pressure power outlet mother wire and is connected by on-load switch QL11, fuse FU11 and earthed switch QE11 on on-load switch QL11, have been provided with, on-load switch QL11 upside-down mounting in the line, metering cabinet is the electric power meter of distribution system, the outlet method of metering cabinet is outlet under cable.Wherein, service entrance switch is provided with switch gate cashier's office in a shop, is provided with middle switch gate on transformer, and outlet switch is provided with lower switch gate cashier's office in a shop, on lower switch gate, is provided with band electromagnetic lock.
The utility model, by conventional primary system configuration incoming line cabinet built-in switch (not being with fuse and earthed switch), changes the on-load switch QL11 with fuse and earthed switch into; Formal dress connection in legacy system changes upside-down mounting into, switch cubicle monnolithic case size constancy, and construction profile, by original two doors up and down, changes three switch gates of upper, middle and lower into.Metering cabinet profile remains unchanged, and just changes the copper bar connection of former scheme into cable and directly descends outlet.Like this, by the inspection earthing function of the fuse short-circuit protection function of the isolation features of incoming line switch cabinet and outlet switch cabinet and earthed switch, with a load of the upside-down mounting with fuse FU11 and earthed switch QE11, open QL11 and close realization.Lower switch gate band electromagnetic lock, by the forced blocking of on-load switch incoming power end, prevents mistakenly entering charged chamber.
In addition, the primary system that the utility model forms with two switch cubicles, three functions that switch cubicle configuration just can reach have been reached, directly save a switch cubicle, and correspondingly reduce key dimension of the present utility model, the minimizing of switch cubicle and saved capital construction land used, has directly reduced production cost, has promoted the ability of product competitiveness and total solution.
By reference to the accompanying drawings embodiment of the present utility model is explained in detail above, but the utility model is not limited to above-described embodiment, in the ken possessing those of ordinary skills, can also under the prerequisite that does not depart from the utility model aim, make a variety of changes.
