Problems solved by technology

[0004] In the existing ring network cabinets, both the L cabinet and the V cabinet mechanism have the locking function of the program lock, and both can realize the locking function when the dual power supply is supplied, that is, only one incoming line L cabinet can be closed at the same time, while the other Incoming line L cabinet cannot be operated
[0005] When the F cabinet is used as the incoming line, there is no program lock and interlock at present. For the ring main unit that uses the F cabinet as the dual power incoming line, it obviously cannot meet the reliability requirements of the power supply.

Embodiment Construction

[0016] The following will be combined with figure 1 , 2 The present invention is introduced in detail: the present invention comprises an interlock mechanism 1 and a program lock 2 for inserting a key. The interlocking piece 3 is in contact with the cabinet body 4, and the other side of the program lock 2 is in contact with the front end of the interlocking mechanism 1; the rear end of the interlocking mechanism 1 is equipped with an energy storage spring 5. The energy storage spring 5 is close to the interlock mechanism 1 after energy storage.

[0017] Both sides of the program lock 2 are respectively provided with a left lock head 21 and a right lock head 22, and the front of the program lock 2 is provided with a socket 23 for inserting a key.

[0018] The left lock head 21 of the program lock 2 abuts against the front end side of the interlock mechanism 1 after the energy storage spring 5 is charged.

[0019] The right lock head 22 of the program lock 2 is in contact wit...

Abstract

The invention relates to a program lock interlocking device of a ring network cabinet, comprising an interlock mechanism and a program lock for inserting a key. The program lock is installed on the front end of the interlock mechanism, and one side of the program lock is connected to the The interlocking piece is slidably connected to the cabinet body, and the other side of the program lock is in contact with the front end of the interlocking mechanism; the rear end of the interlocking mechanism is equipped with an energy storage spring, which stores energy close to the interlocking mechanism; the beneficial effect of the present invention is: through the mutual cooperation of the interlocking mechanism and the program lock to form a two-lock-one-key interlocking device, the existing F cabinet double power supply incoming line can be realized, and the middle female Connected mechanical interlocking to ensure the safety and reliability of power supply.

Description

technical field [0001] The invention belongs to the technical field of double-circuit power supply interlocking protection of ring network cabinets, and in particular relates to a program lock interlocking device for F cabinets in ring network cabinets. Background technique [0002] In the current distribution network system, in order to improve the reliability and stability of power supply, many power supply loops are used for power supply. When one power supply system fails, it can be quickly switched to another power supply system to ensure continuous power supply. [0003] In the power system, due to certain differences in frequency, voltage, current, and power factors, the two power systems are not allowed to be directly connected in series for power supply. During normal power supply, only one power supply system plays a role, while the other power supply system acts as a backup power supply. This requires a locking device between the two power systems to ensure that ...
