Fig. 1 is a schematic structural diagram of the present invention;
FIG. 2 is a schematic view of the connection relationship between the inclined plate and the left and right side plates of the cable chamber of the present invention;
the labels in the figure are: 1. the device comprises a left side plate, a PT (potential Transformer) base plate 2, a PT (potential Transformer) base plate 3, a PT base plate 4, an inclined plate 5, a rear sealing plate 6, a rear pressure relief plate 7, a door plate 8 and a right side plate.
Detailed Description
In order to make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the following will combine the drawings in the present invention to clearly and completely describe the technical solution in the embodiments of the present invention, and obviously, the described embodiments are some embodiments of the present invention, rather than all embodiments, based on the embodiments in the present invention, all other embodiments obtained by a person of ordinary skill in the art without creative work belong to the protection scope of the present invention.
As shown in fig. 1 and 2, a downward pressure relief structure of a cable chamber of a voltage transformer cabinet comprises an air box with an explosion-proof valve mounted at the bottom and mounted on the cable chamber, wherein a sloping plate 4 of the cable chamber is mounted between a left side plate 1 and a right side plate 8, the sloping plate 4 is provided with a rivet nut hole and a rivet nut, a PT bottom plate 3 is riveted with the left and right side plates, PT 2 is mounted on the PT bottom plate 3 and connected with a sleeve by a flexible cable, the height of the PT bottom plate 3 is greater than 50mm, the end of the PT bottom plate 3 is designed with a knock-off hole, the rivet nut hole is opened and the rivet nut is pulled to mount a rear pressure relief plate 6 on the PT bottom plate 3 and the rivet nut of the sloping plate 4 for fixing, the rear pressure relief plate 6 divides the internal cavity of the air box into a PT chamber at the front end and a pressure relief channel at the rear end, in the embodiment, the sloping plate 4 is an angle plate, the higher end of, the pressure release hole can satisfy PT 2 backward pressure release to pressure release channel, and pressure release channel's the mouth of drawing forth is PT bottom plate 3 hits the hole that falls, and when having powerful pressure explosion in the pressure release channel, 3 terminal hits the hole that falls of PT bottom plate and is hit and fall to the cable pit of pressure release. When strong pressure explodes in the PT chamber, the rear pressure relief plate 6 is knocked down backwards and then enters the pressure relief channel, and the knocking down hole at the tail end of the PT bottom plate is knocked down, so that pressure is relieved to the cable trench.
The utility model discloses an adopt flexible cable, PT bottom plate 3 and back pressure release board 6's mounting means to realize the downward pressure release of voltage transformer cabinet, facilitate field installation and use.
