Description

Technical Field

[0001] The present application relates to the technical field of box-type substations, and in particular to an American box-type substation. Background Art

[0002] The American box-type substation originated in the 20th century and is a new type of outdoor complete substation. Its development is closely related to the development and demand of the power industry. This type of substation has the advantages of flexible combination, easy transportation and installation, short construction period, low operating cost, no pollution, and maintenance-free, so it is widely used in the power industry.

[0003] In the related art, an American box-type substation usually includes a box body and electrical equipment located inside the box body. At the same time, double-sided box doors are arranged on the box body, and the electrical equipment is usually fixed on the inner side of the box body. Since the box-type substation is usually exposed to the outdoor environment, the setting of double-layer box doors can increase the safety of operators, improve the safety and reliability of equipment, and improve the sealing and dustproof performance of equipment.

[0004] When workers inspect and repair a box-type substation, they need to unlock and open the two doors of the box in turn, and then inspect the electrical equipment installed on the inner side of the box. The space inside the box is usually narrow and there are many cables. The narrow space makes it difficult for workers to move and operate, and the use of large maintenance tools may be even more difficult, resulting in low maintenance efficiency. There is room for improvement. Utility Model Content

DETAILED DESCRIPTION

[0037] The present application is further described in detail below in conjunction with all the accompanying drawings.

[0038] Example:

[0039] Reference Figure 1 , Figure 2 and Figure 3 An American box-type substation comprises a box body 1 and a box door 2 installed on the box body 1, and an inspection port 11 and an inspection door 3 for blocking the inspection port 11 are provided on the side of the box body 1 away from the box door 2. One side of the inspection door 3 is hinged to the box body 1, and a locking assembly 4 for connecting the inspection door 3 to the box body 1 is provided on the inspection door 3; when it is necessary to inspect the electrical equipment inside the box body 1, the inspection door 3 can be opened by the locking assembly 4, and the electrical equipment inside the box body 1 can be directly inspected, so as to improve the inspection efficiency of the box-type substation.

[0040] Reference Figure 3 and Figure 4 The locking assembly 4 includes an operating handle 41 arranged on the outer side of the inspection door 3, a transmission member 42 arranged on the inner side of the inspection door 3, and a locking pin 43 connected to one end of the transmission member 42. A locking groove 12 for inserting the locking pin 43 is opened on the side wall of the inspection port 11; the operating handle 41 drives the locking pin 43 to reciprocate in the direction close to the locking groove 12 through the transmission member 42, thereby realizing the locking and unlocking of the inspection door 3.

[0041] Reference Figure 5 and Figure 6The transmission member 42 includes a transmission rod 421 and a rotating plate 422 rotatably connected to the inner side surface of the inspection door 3. A rotating shaft 4221 is fixedly installed in the middle of one side of the rotating plate 422. The inspection door 3 is provided with a mounting through hole 13 for the rotating shaft 4221 to pass through. The end of the rotating shaft 4221 away from the rotating plate 422 is connected to the operating handle 41. The rotation of the operating handle 41 around the axis of the rotating shaft 4221 will drive the rotating plate 422 to rotate synchronously.

[0042] Reference Figure 5 and Figure 7 The two ends of the transmission rod 421 are respectively hinged to the outer circumference of the rotating plate 422 and one end of the locking pin 43; a limit block 14 is welded and fixed to the inner side of the inspection door 3 to limit the position of the locking pin 43, and a limit hole 141 is provided on the limit block 14 for the locking pin 43 to pass through and slide, so that the locking pin 43 can slide up and down in the vertical direction (the locking pin 43 does not fall out of the limit hole 141 at the extreme position of sliding downward). The staff controls the operating handle 41 to rotate around the rotating shaft 4221 (see Figure 6 ) rotates along its axis, thereby driving the rotating plate 422 and the transmission rod 421 to move, so that the locking pin 43 is inserted into or removed from the locking groove 12.

[0043] Reference Figure 6 The operating handle 41 is hinged to the end of the rotating shaft 4221 away from the rotating plate 422, and a placement groove 15 is provided on the outer side of the inspection door 3 for the operating handle 41 to be rotated and placed. This arrangement facilitates the storage of the operating handle 41 and reduces the possibility of an unauthorized person accidentally touching the operating handle 41 to lock or unlock the inspection door 3.

[0044] Reference Figure 5 and Figure 6 A hinge shaft 4222 is fixedly provided at the end of the rotating shaft 4221 away from the rotating plate 422, and a hinge hole 411 for the hinge shaft 4222 to pass through is opened on the operating handle 41, and the cross-sectional shape of the hinge hole 411 is waist-shaped; a limit hook 151 is welded and fixed on the inner wall of the placement sink 15, and a limit slot 412 for the limit hook 151 to be inserted is opened on the operating handle 41; when the operating handle 41 is rotated to the inside of the placement sink 15, due to the setting of the hinge hole 411 with a waist-shaped cross-section, the limit hook 151 can pass through the inside of the limit slot 412, thereby limiting the operating handle 41, reducing the possibility of the operating handle 41 rotating out of the placement sink 15 in a natural state.

[0045] Reference Figure 5 and Figure 6The inspection door 3 is hinged with a baffle 5 on the upper edge of the opening of the trough 15, so as to reduce the possibility of external dust or impurities entering the interior of the trough 15, and at the same time further reduce the possibility of unauthorized persons turning the operating handle 41 and unlocking the inspection door 3; the inspection door 3 is fixedly provided with a first magnetic block 152 on the lower edge of the opening of the trough 15, and the baffle 5 is provided with a second magnetic block 51 that attracts the first magnetic block 152; when the baffle 5 blocks the opening of the trough 15, one side of the first magnetic block 152 abuts against one side of the second magnetic block 51.

[0046] Reference Figure 7 and Figure 8 The outer side surface of the inspection door 3 is provided with a third magnetic block 16 which attracts the second magnetic block 51; when the baffle 5 rotates upward to a position in contact with the outer side surface of the inspection door 3, the second magnetic block 51 is close to the third magnetic block 16; with this arrangement, when the staff rotates the operating handle 41, the baffle 5 is rotated upward to a position in contact with the outer side surface of the inspection door 3, and the second magnetic block 51 and the third magnetic block 16 have a magnetic attraction force that attracts each other, thereby reducing the possibility of the baffle 5 rotating downward to interfere with the rotation of the operating handle 41 at this time.

[0047] The implementation principle of the embodiment of the present application is:

[0048] When it is necessary to inspect and repair the electrical equipment inside the box 1, the baffle 5 is rotated upward and fixed by the magnetic attraction between the second magnetic block 51 and the third magnetic block 16. At this time, the operating handle 41 is moved upward for a while and then rotated around the hinge shaft 4222 to release the lock of the operating handle 41 by the limit hook 151; the staff controls the operating handle 41 to rotate around the axis of the rotating shaft 4221, thereby driving the rotating plate 422 and the transmission rod 421 on the rotating plate 422 to move, so that the locking pin 43 disengages from the locking groove 12, thereby releasing the lock of the inspection door 3 and the box 1; the staff can directly inspect the electrical equipment installed inside the box 1 through the inspection port 11.
