Abstract
Compact-type high-pressure metering cabinet, relates to the structure-design technique of power transmission and distribution technical field, particularly metering cabinet.Comprise the cabinet being provided with measuring room and hyperbaric chamber, current transformer, voltage transformer, fuse, copper bar are set in hyperbaric chamber, it is characterized in that placing left and right spelling cabinet tubulose bus respectively in cabinet arranged on left and right sides, be connected to one end of a T junction correspondingly in the inner of cabinet at each left and right spelling cabinet tubulose bus, the other end of each T junction is connected with current transformer, voltage transformer, fuse by copper bar correspondingly, and the 3rd end of each T junction arranges insulation shutoff respectively.The utility model adopts left and right spelling cabinet tubulose bus, with joint, left and right side is spelled cabinet to be directly connected with the signal of metering cabinet, and eliminate the mode that the straight-through cabinet transition of employing two transmits the signal of telecommunication, to meet power equipment to floor space, reliability, cost, requirement that after-sales service aspect is higher.
Description
Technical field
The utility model relates to the structure-design technique of power transmission and distribution technical field, particularly metering cabinet.
Background technology
At present, on market, existing metering cabinet insulation mode has compound inslation formula, air-insulated type and solid insulation formula.Wherein, the cabinet of compound inslation formula and air-insulated type is heavier, and cabinet type is larger, and take up an area space greatly, carrying is inconvenient; There is Railway Project in solid insulation formula metering cabinet: the incoming line cabinet 1, for giving metering cabinet through-flow, must increase the straight-through cabinet of one side for providing inlet wire branch to metering cabinet; 2, for the outgoing line cabinet of metering cabinet outlet, need to increase separately the straight-through cabinet of one side, good several times cupboard is stitched together often, removing metering cabinet, at least also needs in addition to increase two sides auxiliary tank type, just function of measuring can be completed, indirectly cause bulky, take up an area space greatly, cost is high, carrying inconvenience, dismounting, installation are also inconvenient.
Utility model content
The purpose of this utility model is to provide that a kind of floor space is little, the compact-type high-pressure metering cabinet of good reliability.
The utility model comprises the cabinet being provided with measuring room and hyperbaric chamber, current transformer, voltage transformer, fuse, copper bar are set in hyperbaric chamber, it is characterized in that placing left and right spelling cabinet tubulose bus respectively in cabinet arranged on left and right sides, each left and right spelling cabinet tubulose bus is connected to one end of a T junction correspondingly in the inner of cabinet, the other end of each T junction is connected with current transformer, voltage transformer, fuse by copper bar correspondingly, and the 3rd end of each T junction arranges insulation shutoff respectively; The inner core of described left and right spelling cabinet tubulose bus and T junction is electric conductor, at electric conductor outer cladding insulating material.
Before work, each left and right in cabinet outer end is spelled cabinet tubulose bus and be inserted into accordingly in bus hole corresponding to incoming line cabinet, outgoing line cabinet pole.During energising work, current and voltage signals is through incoming line cabinet, spell cabinet tubulose bus by left side, spell T junction that cabinet tubulose bus is connected with left side and flow into the copper bar of inside, hyperbaric chamber, fuse, current transformer and voltage transformer, again via copper bar, to spell T junction that cabinet tubulose bus is connected with right side, right side spells cabinet tubulose bus and enters outgoing line cabinet, outgoing line cabinet can directly connect various load.
The weak current signal that current transformer and voltage transformer obtain and weak voltage signal are through the output light current binding post of current transformer and voltage transformer, measuring room is connected to secondary wiring, link together with the gauge table of various function, thus realize function of measuring.
The utility model insulation mode and mounting means, cost performance is high, compact conformation, parts are few, dismantle and be installed as can withdraw-type operating structure, easy to maintenance, metering more accurately, metering device reliably.The utility model adopts left and right spelling cabinet tubulose bus, with joint, left and right side is spelled cabinet to be directly connected with the signal of metering cabinet, and eliminate the mode that the straight-through cabinet transition of employing two transmits the signal of telecommunication, to meet power equipment to floor space, reliability, cost, requirement that after-sales service aspect is higher.
In order to reach all insulation, improve fail safe, described T junction is connected with corresponding left and right spelling cabinet tubulose bus respectively by fastening screw mandrel.
Accompanying drawing explanation
Fig. 1 is a kind of structural representation of the present utility model.
Fig. 2 is the left side schematic diagram of Fig. 1.
Fig. 3 is that figure schematic diagram is found in the amplification at incoming line cabinet place of the present utility model.
Fig. 4 is the side direction cut-away view of Fig. 3.
Embodiment
As shown in Figure 1,2,3, 4, the utility model is provided with cabinet body frame 2, and be measuring room 15 at cabinet body frame 2 internal upper part, bottom is provided with hyperbaric chamber 17.
Measuring room 15 inside is provided with the metering and display devices such as gauge table.
One group of current transformer, 7, one group of voltage transformer, 8, two groups of fuses 9 and some copper bars 16 are equipped with in inside, hyperbaric chamber 17.Three groups of left spelling cabinet tubulose buses 3,4,12 are installed on the left of the cabinet body frame 2 in hyperbaric chamber 17 with placing, three groups of right sides are installed with also placing on the right side of cabinet body frame 2 equally and receive at the counter tubulose bus.
The left spelling cabinet tubulose bus 3 of cabinet the inner is connected to by fastening screw mandrel 14 one end of T junction 11, the left spelling cabinet tubulose bus 4 of cabinet the inner also connects T junction 5 by fastening screw mandrel according to this, the left spelling cabinet tubulose bus 12 of cabinet the inner connects T junction 13 by fastening screw mandrel; The other end of T junction 11,5,13 is connected on a copper bar 16 separately.
Also be connected to separately on copper bar 16 respectively by respective joint by identical mode at three groups of right spelling cabinet tubulose buses of cabinet the inner.
Insulation shutoff 6 shutoff is used respectively at the 3rd end of the aerial T junction 11,5,13 of each exposure.
The other end of copper bar 16 or be connected with current transformer 7, the other end of copper bar 16 or be connected with voltage transformer 8 by fuse 9.
In addition, left and right spelling cabinet tubulose bus, as shown in Figure 4, by such as tubulose copper material 3-1 and be coated on outer insulating material 3-2 and form.T junction 11 is made up of the electric conductor 11-1 of inside and the outer insulating material 11-2 that is coated on outside it.Also roughly the same, just length is different, to facilitate connection for other T junction 5,13 structure.
In Fig. 3,4, A portion is pole in incoming line cabinet.
During work energising, current and voltage signals is through incoming line cabinet 1, by cabinet tubulose bus is spelled in left side, T junction, copper bar 16, fuse 9 flow into inside, hyperbaric chamber 17 current transformer 7 and voltage transformer 8, then spell cabinet tubulose bus enter outgoing line cabinet 10 via copper bar 16, T junction, right side.
