Description

TECHNICAL FIELD

[0001] The application belongs to the technical field of electric power engineering, and particularly relates to a cable chamber with a door interlocking structure. BACKGROUND

[0002] The rear half of a medium-voltage switch cabinet is a cable chamber, and components of the cable chamber are fixedly installed. When the switch cabinet is overhauled and maintained, the cable chamber is mainly targeted. When the rear door of the cable chamber is opened under the condition of electrification, the person mistakenly enters the electrified isolation, which does not meet the five-prevention requirements of the medium-voltage switch equipment. A commonly used interlocking method is to interlock the grounding switch and the rear door of the cable chamber.

[0003] In the prior art, because the medium-voltage switch equipment is relatively large in size, the rear door of the cable chamber is generally divided into an upper door and a lower door. However, an interlocking relationship is usually only designed between the grounding switch and the lower door, and the grounding switch can only be disconnected after the lower door is opened. This method ignores the protection of the upper door. If the upper door is opened alone, the grounding switch is still in a closed state because the lower door is not opened, and at this time, the risk of electric shock is easy to occur, and there is a certain safety hazard.

[0022] Please refer to Figures 1 to 5 A cable room with door interlocking structure is provided. The cable room with door interlocking structure comprises a box body 10, a mounting bracket 20, an upper locking assembly 30 and a lower locking assembly 40. The box body 10 has a receiving cavity for mounting components. The box body 10 is provided with an opening communicating with the receiving cavity. The opening is arranged with an upper door 50 and a lower door 60. The mounting bracket 20 is fixedly arranged in the receiving cavity. The upper locking assembly 30 is slidingly arranged on the mounting bracket 20 and connected with the upper door 50. The upper locking assembly 30 has a positioning portion 313. The lower locking assembly 40 is arranged on the mounting bracket 20 and corresponds to the lower door 60. The lower locking assembly 40 has a plug-in portion which can slide along the vertical direction and correspond to the positioning portion 313. During the closing process of the upper door 50, the upper locking assembly 30 is moved. Then, during the closing process of the lower door 60, the plug-in portion is inserted into the positioning portion 313 through the lower locking assembly 40 to fix the sliding position of the upper locking assembly 30.

[0023] In this embodiment, the box body 10 has a receiving cavity, and components are mounted in the receiving cavity. The box body 10 is provided with an opening communicating with the receiving cavity, and the opening is arranged with an upper door 50 and a lower door 60. The mounting bracket 20 is fixedly arranged in the receiving cavity. The upper locking assembly 30 is slidingly arranged on the mounting bracket 20 and connected with the upper door 50. The upper locking assembly 30 has a positioning portion 313. The lower locking assembly 40 is arranged on the mounting bracket 20 and corresponds to the lower door 60. The lower locking assembly 40 has a plug-in portion which corresponds to the positioning portion 313. The plug-in portion can slide along the vertical direction, so that during the closing process of the lower door 60, the plug-in portion is inserted into the positioning portion 313 through the lower locking assembly 40 to fix the sliding position of the upper locking assembly 30.

[0024] After the upper door 50 is closed, the plug-in portion of the lower locking assembly 40 can be inserted into the positioning portion 313. The lower door 60 is closed, and at this time the lower locking assembly 40 fixes the sliding position of the upper locking assembly 30, so that the upper locking assembly 30 cannot be moved and the upper door 50 cannot be opened. After the lower door 60 is opened, the lower locking assembly 40 releases the position limiting of the upper locking assembly 30, and the upper door 50 can be opened or closed.

After the lower door 60 is opened, the lower locking assembly 40 releases the position limitation of the upper locking assembly 30, and the upper door 50 can be opened or closed. Therefore, the upper door 50 and the lower door 60 are associated with each other, and only when the lower door 60 is opened can the upper door 50 be opened, so as to avoid electric shock and improve the safety during maintenance.

[0026] It should be noted that after the lower door 60 is closed, the lower door 60 can be locked by a door lock to avoid automatic opening of the lower door 60 in bad weather (the lower door 60 is hinged to the box body 10), thereby improving safety. The door lock can be of the prior art.

[0027] In some embodiments, referring to Figures 2 to 5 The upper locking assembly 30 includes a moving piece 31, a sliding block 32 and a push rod 33. The moving piece 31 is connected with the upper door 50 and slides along the horizontal direction. The positioning portion 313 is arranged on the moving piece 31. The sliding direction of the moving piece 31 is set as the first direction. The sliding block 32 is connected with the side of the moving piece 31 away from the upper door 50 and slidingly arranged on the mounting bracket 20 along the first direction. The push rod 33 is arranged along the first direction, one end of the push rod 33 is connected with the sliding block 32, the other end of the push rod 33 extends out of the mounting bracket 20, and the extending end of the push rod 33 has a limiting block 34. In this embodiment, the moving piece 31 slides along the horizontal direction and is connected with the upper door 50, so as to drive the upper door 50 to close or open by the movement of the moving piece 31. The sliding block 32 is connected with the side of the moving piece 31 away from the upper door 50 and slidingly arranged on the mounting bracket 20 along the first direction. The push rod 33 is arranged along the first direction, one end of the push rod 33 is connected with the sliding block 32, the other end of the push rod 33 extends out of the mounting bracket 20, and the extending end of the push rod 33 has a limiting block 34, so as to avoid the push rod 33 from sliding off the mounting bracket 20 in the process of moving the moving piece 31.

[0028] Further, the moving piece 31 comprises a sliding plate 311, a connecting rod 312, and an adapter plate 314. The sliding plate 311 is connected to the sliding block 32 at one end, and the sliding plate 311 is provided with a positioning hole which is adapted to the insertion part.
