Specific embodiment
As shown in Figures 1 to 4, a kind of high-tension switch cabinet with quick pressure relief device, including cabinet body 1, functional compartments, pressure release
Device 3 and backplate 7；The inner space of cabinet body 1 by partition formed functional compartments, the top surface of functional compartments be located at the upper surface of cabinet body 1,
And it is provided with opening；The quantity of functional compartments is 3, respectively interruption chambe 2-1, bus-bar room 2-2 and cable vault 2-3；Pressure relief device 3
Quantity be 3, and be located at the overthe openings of interruption chambe 2-1, bus-bar room 2-2 and cable vault 2-3.
Pressure relief device 3 includes first boss 4-1, second boss 4-2, cover board 5, the first connector 6-1, the second connector 6-
2；First boss 4-1 and second boss 4-2 is symmetrically fixed on the opening two sides of functional compartments, cover board 5 be set to first boss 4-1 and
Above second boss 4-2, the side of cover board 5 is flexibly connected by the first connector 6-1 with first boss 4-1, and the other side passes through
Second connector 6-2 is connect with second boss 4-2；First connector 6-1 includes fixing seat 6-11, connecting shaft 6-12, sleeve 6-
13, the quantity of connecting rod 6-14, fixing seat 6-11 are 2 and are oppositely arranged that the both ends of connecting shaft 6-12 are individually fixed in 2 admittedly
On reservation 6-11, sleeve 6-13 is set on connecting shaft 6-12, and one end of connecting rod 6-14 is fixed on sleeve 6-13, and the other end is solid
Due to the side of cover board 5, the quantity of the first connector 6-1 is 2, and is successively disposed adjacent；Second connector 6-2 includes fixing
Ring 6-21, spring 6-22, spacing ball 6-23, stop collar 6-24, fixed ring 6-21 are fixed below cover board 5, and the one of spring 6-22
End is fixed on fixed ring 6-21, and the other end is connected with spacing ball 6-23, and second boss 4-2 is fixed in one end of stop collar 6-24
On, other end setting is jagged, and spacing ball 6-23 passes through the notch of stop collar 6-24 and is located inside stop collar 6-24, stop collar
The material of 6-24 is elastomeric material, such as rubber；The quantity of second connector 6-2 is 2~3, and is successively disposed adjacent.
The structure of backplate 7 is rectangular closed-loop construct, and is located at lower section, first boss 4-1 and the second boss of cover board 5
Between 4-2；The side adjacent with second boss 4-2 of backplate 7 offers through-hole 7-1.
The working principle for having the high-tension switch cabinet of quick pressure relief device using the utility model is, when high-tension switch cabinet exists
When arcing failure occurring in use process, bulk gas can be discharged in functional compartments, the cover board 5 positioned at functional compartments overthe openings is being pressed
It is lifted up under power effect.At this point, the side due to cover board 5 is connect by the second connector 6-2 with second boss 4-2, so that
During cover board 5 is lifted up under gas pressure effect, the spring 6-22 of the second connector 6-2 is constantly stretched；With this
Simultaneously as spacing ball 6-23 is located in stop collar 6-24, and stop collar 6-24 is fixed on second boss 4-2, thus is worked as
When gas pressure is lower, the amplitude that cover board 5 is lifted up is little, only opens an osculum, and the gas inside functional compartments passes through this
A osculum releases, and plays the role of pressure release, after the pressure inside functional compartments is released, cover board 5 in self gravity and
Under the pulling force effect of spring 6-22, restores the state that lid closes, influence is had no on the structure of pressure relief device, can continue to come into operation.
If the gas pressure discharged in functional compartments is quite big, the meeting of cover board 5 is by the impacting with high pressure of abrupt release and lifts rapidly upward, by
It is elastomeric material in the material of stop collar 6-24, has certain elasticity, when the upward power of cover board 5 is sufficiently large, spacing ball
6-23 can be detached from the limitation of stop collar 6-24 from the indentation, there of stop collar 6-24, and then entire cover board 5 is dug upwards, same with this
When, since the other side of cover board 5 is flexibly connected by the first connector 6-1 with first boss 4-1, and first boss 4-1 is solid
Due on cabinet body 1, thus, cover board 5 under the action of the first connector 6-1 without departing from cabinet body 1, only can be around the first connector 6-
1 connecting shaft 6-12 rotation, the safety accidents such as injures by a crashing object caused by avoiding cover board 5 from falling off.Meanwhile stop collar 6-24 is fixed on second
On boss 4-2, spring 6-22, spacing ball 6-23 are fixed on cover board 5 by fixed ring 6-21, thus, even if spacing ball 6-23
It is detached from the limitation of stop collar 6-24, is also detached from or is splashed out outside pressure relief device without any components, security level is higher.In addition, logical
Setting backplate 7 is crossed, so that entire pressure relief device is in routine use, cover board 5 covers the even closer of conjunction, effectively avoids blowing and raining
Equal bad weathers erosion damage caused by component in cabinet body 1 etc., meanwhile, the side adjacent with second boss 4-2 of backplate 7 is opened
Equipped with through-hole 7-1, when so that the amplitude lifted of cover board 5 is lower, the pressure inside functional compartments can be released by through-hole 7-1
It puts.
