Specific embodiment
With reference to the accompanying drawing and specific embodiment is further described the utility model.
Embodiment one
As shown in Figure 1, the present embodiment discloses a kind of switchgear, including low-pressure chamber 1, breaker chamber 2, maintenance room 3, small mother
Line room 4, bus-bar room 8 make somebody a mere figurehead inlet wire rear secondary cabinet 9 and cable vault 10, and the aerial inlet wire rear secondary cabinet 9 on rear side of switchgear is equipped with arcing
Channel A, each compartment of switchgear and arcing channel A's is designed as existing design, is no longer described in detail herein.
The present embodiment is the guiding role preferably realized to arcing energy, the space of arcing release is increased, to subtract
Lack the percussion of arcing energy, and devises a kind of novel arcing channel design in inside switch cabinet.
As shown in Fig. 1, Fig. 3-6, inside switch cabinet arcing channel design, including be installed on bus-bar room 8 and cable vault 10 it
Between unidirectionally controlled component 11, unidirectionally controlled component 11 is installed on bus-bar room partition 12.Specific design is unidirectionally controlled group
Part 11 includes being fixedly installed on the outside of one group of pressure relief plate 11-1, each pressure relief plate 11-1 being mounted side by side by metal bolts 11-2
On bus-bar room partition 12, inside is fixedly installed on bus-bar room partition 12 by plastic bolt 11-3.
10 bottom of cable vault is connected to maintenance room 3 and arcing channel A respectively, and 10 top of cable vault is connected to arcing channel A,
It is equipped with the bus-bar room arcing channel 6 for arcing pressure release at the top of bus-bar room 8, the electricity for arcing pressure release is equipped at the top of cable vault 10
Cable room arcing channel 7.
When no arcing occurs, unidirectionally controlled component 11 is mounted on 12 top of bus-bar room partition, is blocked by partition, arcing is logical
The unidirectionally controlled component 11 in road can be in close state under the effect of gravity, in this state, it can be ensured that bus
Protection level requirements between room and cable vault.
When arcing occurs for cable vault, since unidirectionally controlled component 11 is between bus-bar room 8 and cable vault 10, arcing energy
Amount can impact the pressure relief plate 11-1 of unidirectionally controlled component 11 to which one way component is opened, as shown in Fig. 2, bus-bar room 8 and electricity
Cable room 10 is connected to, and constitutes arcing channel B.A portion arcing energy will flow up in this way, by arcing channel B, most
It is released eventually by the arc baffle of letting out in bus-bar room arcing channel 6, a part of arcing energy is by arcing channel A, eventually by cable
The arc baffle of letting out in room arcing channel 7 releases, and arcing energy flows to shown in the arrow in visible Fig. 1.Finally realize to arcing energy
The shunting function of amount reduces the percussion of arcing energy；If being not provided with this component, arcing is only along the (combustion of a channel
Arc channel A) pressure release, passway path length, can switch cabinet door and side plate generate powerful impact force and burn so that arcing is from door
Place sprays and scaling loss switchs cabinet side panel, the failure for causing arcing to test.
Embodiment two
As shown in Figure 1, the arcing channel at the top of switchgear include the top of breaker chamber 2 breaker chamber arcing channel 5,
The cable vault arcing channel 7 in bus-bar room arcing channel 6,10 top of cable vault at the top of bus-bar room 8, the present embodiment two is in addition to implementing
The breaker chamber arcing channel 5 at top, bus-bar room are also fired in the arcing channel of switchgear designed by example one and inside switch cabinet
The structure in arc channel 6 and cable vault arcing channel 7 optimizes.
It is specific as follows:
First by 7 heightening design of breaker chamber arcing channel 5, bus-bar room arcing channel 6 and cable vault arcing channel, increase
The space in arcing channel；Then their door-plate is optimized.
As shown in fig. 7, being equipped with cabinet top cover in breaker chamber arcing channel 5 and cable vault arcing channel 7, top sets disconnected respectively
Road device room arcing channel pressure relief plate 13 and cable vault arcing channel pressure relief plate 15；Band arcing is equipped in bus-bar room arcing channel 6 to keep off
The cabinet top cover of plate, top set bus-bar room arcing channel pressure relief plate 14.
Wherein, breaker chamber arcing is fixedly installed in by metal bolts on the outside of breaker chamber arcing channel pressure relief plate 13 to lead to
On road 5, inside is fixed by plastic bolt；Electricity is fixedly installed in by metal bolts on the outside of cable vault arcing channel pressure relief plate 15
On cable room arcing channel 7, inside is fixed by plastic bolt；Bus-bar room arcing channel pressure relief plate 14 includes a pair, each pressure release
The outside of plate is fixed by metal bolts, inside is fixed by plastic bolt.
When no arcing occurs, breaker chamber arcing channel 5, bus-bar room arcing channel 6 and cable vault arcing channel 7
Pressure relief plate can be fixed on solid with plastic bolt under the effect of gravity and on the edge of opening direction, make at
In closed state, in this state, so that it may guarantee the protection level requirements of switchgear.
When arcing occurs, arcing energy can be on the switch gate along arcing channel impulse to arcing channel, thus combustion
Plastic bolt on arc access door is opened to impact.And the opening state of four doors is at " pyramid " shape, as shown in Fig. 7 and Fig. 8,
Arcing energy can be controlled eruption upwards by being somebody's turn to do " pyramid " shape door, without erupting around.Therefore it is kept away in arcing type approval test
Having exempted from arcing can fall that (according to the regulation that arcing is tested, indicator can be put into the surrounding 300mm of cabinet body to be tested in indicator
Place) on to make the danger of test failure.
Certainly, the above description is not intended to limit the present invention, and the utility model is also not limited to the example above, this
The those of ordinary skill of technical field, in the essential scope of the utility model, the variations, modifications, additions or substitutions made, all
It should belong to the protection scope of the utility model.
