Description

A prefabricated substation with pressure relief structure

Technical Field

The utility model relates to the technical field of prefabricated transformer substations, and more specifically, to a prefabricated transformer substation with a pressure relief structure.

Background Art

Box-type substation, also known as prefabricated substation or prefabricated substation, is a kind of high-voltage switchgear, distribution transformer and low-voltage distribution device, which are prefabricated indoor and outdoor compact distribution equipment arranged in one according to a certain wiring scheme. It organically combines the functions of transformer step-down and low-voltage distribution, and is installed in a moisture-proof, rust-proof, dust-proof, rodent-proof, fire-proof, theft-proof, heat-insulating, fully enclosed and movable steel structure box.

The utility model with announcement number CN216564241U discloses a high-voltage prefabricated substation with a stable transfer structure. The high-voltage prefabricated substation with a stable transfer structure attracts the magnetic block on the baffle to the metal shell of the prefabricated substation body. In rainy weather, the baffle is rotated downward along the mounting block through a rotating shaft, and then the support rod on the baffle is rotated so that the docking block at the bottom of the support rod is docked with the docking groove on the limit seat, and the baffle is limited. The baffle is used to block rainwater on the outside of the ventilation window, thereby preventing rainwater from entering the interior of the prefabricated substation body.

When the above patent is in use, the distance between the prefabricated substation body and the ground is increased by setting the base, thereby facilitating the assembly between the base and the prefabricated substation body. However, when a short circuit occurs in the substation, the internal pressure of the substation will increase sharply. However, this structure is not convenient for releasing the internal pressure, which may cause equipment damage or even explosion, posing certain safety hazards.

Obviously, the described embodiment is a part of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

Referring to Figures 1-4 of the specification, a prefabricated substation with a pressure relief structure in this embodiment includes a prefabricated substation body 1, a connecting tube 2 is fixedly connected at the top center position of the prefabricated substation body 1, a fixing box 3 is fixedly connected to the top of the connecting tube 2, an extrusion column 9 is movably provided inside the connecting tube 2, a switch 6 is movably provided on the top of the extrusion column 9, and the switch 6 is fixedly installed on the top of the inside of the connecting tube 2, a motor 7 is provided inside the fixing box 3, a sealing assembly 8 is provided on the motor 7, and the sealing assembly 8 includes two horizontal plates 801, two connecting rods 802, four side plates 803, a screw rod 804 and three sliding rods 805, and an alarm 4 is fixedly installed on the front side of the prefabricated substation body 1.

Furthermore, both ends of the two connecting rods 802 are fixedly connected to the opposite sides of the two horizontal plates 801, and the four side plates 803 are fixedly connected to the two horizontal plates 801, and the four side plates 803 are movably arranged on the screw rod 804 and the three sliding rods 805, respectively. One end of the screw rod 804 is fixedly connected to the motor 7, and the three sliding rods 805 are fixedly connected to the fixed box 3. The opposite sides of the two horizontal plates 801 are fixedly connected with sealing gaskets 806, and the opposite sides of the two sealing gaskets 806 are in contact with the fixed box 3.

Furthermore, a ventilation hole is provided at the top of the fixed box 3 , and a filter screen 5 is fixedly connected to the inside of the ventilation hole. By providing the filter screen 5 , external debris is prevented from entering the fixed box 3 .

Furthermore, a limiting assembly is provided on the extrusion column 9, and the limiting assembly includes two side plates 10 and two vertical poles 11. The opposite sides of the two side plates 10 are fixedly connected to the extrusion column 9, and the two side plates 10 are movably mounted on the two vertical poles 11, and the top ends of the two vertical poles 11 are fixedly connected to the connecting tube 2. Springs 12 are movably mounted on the two vertical poles 11, and the two ends of the two springs 12 are fixedly connected to the connecting tube 2 and the two side plates 10, respectively.

Among them, the extrusion column 9 drives the two side plates 10 to slide on the two vertical rods 11 respectively, which can prevent the extrusion column 9 from deflecting when moving vertically. When the two side plates 10 move upward, the two side plates 10 drive the two springs 12 to compress. When the pressure is released, the two springs 12 rebound and drive the two side plates 10 to move downward. The structure is simple and easy to use.

The method of using this embodiment is:

When the internal pressure of the prefabricated substation body 1 increases suddenly, the pressure drives the extrusion column 9 to move upward, and the extrusion column 9 presses the switch 6. Since the alarm 4 and the motor 7 are electrically connected to the switch 6, the switch 6 can control the alarm 4 and the motor 7 to work. The alarm 4 works and emits an alarm sound. The motor 7 drives the screw rod 804 to rotate. Since the screw rod 804 is threadedly connected to one of the side plates 803, and the other side plate 803 cooperates with the slide bar 805 to limit the rotation of the cross plate 801, the screw rod 804 drives the cross plate 801 to move horizontally, thereby driving the sealing gasket 806 to move horizontally and making the sealing gasket 806 away from the connecting tube 2. The internal and external air are exchanged through the fixed box 3 and the connecting tube 2, and the prefabricated substation body 1 is depressurized. The structure is simple and the safety performance is high. Similarly, the motor 7 reverses to drive the sealing gasket 806 to return to its original position. The sealing gasket 806 can improve the sealing between the cross plate 801 and the fixed box 3.
