Description

A ring network cabinet with a device for preventing mis-opening of a cable room

technical field

The utility model relates to the technical field of electric equipment, in particular to a ring network cabinet with a device for preventing misopening of a cable room.

Background technique

At present, there are many kinds of ring network cabinets used in power systems at home and abroad, but the cabinet cable compartment doors of most manufacturers do not have a real interlocking mechanism, and are generally tightened with bolts outside the cable compartment door, and then pass A warning sign is posted to remind users to prevent safety accidents when the cable is switched on and charged, but this method does not realize the real chain action. No matter whether the system is closed or grounded, the cable room door can be easily Easy opening is not conducive to real security protection.

Contents of the invention

The purpose of this utility model is to solve the above-mentioned problems in the structure of the traditional ring network cabinet, and provide a ring network cabinet with a cable room anti-mis-opening device with ingenious design, chain action, and higher safety.

The specific scheme of the utility model is: a ring network cabinet with a device for preventing accidental opening of the cable room, which has a cabinet body, and a circuit breaker mechanism operating room is arranged on the upper part of the cabinet body, and a circuit breaker mechanism is arranged in the circuit breaker mechanism operating room. There is a cable room at the lower part of the body, and a cable room door is opened on the side wall of the cable room. A support plate is provided on the side of the circuit breaker mechanism close to the door of the cable room. A cam locking mechanism is provided above the support plate to lock with the cam. The cam contact connection in the mechanism has a vertically downward spring pin, vertical guide rods are arranged on both sides of the bracket plate, a movable plate is set on the vertical guide rod, a handle is provided on one side of the movable plate, and the bottom of the movable plate is vertical There is a movable latch downward; a set of horizontal limiting device is provided under the bracket plate, and the horizontal limiting device includes a horizontal moving plate and a tension spring. One end of the tension spring is connected with the transverse moving plate, and the other end of the tension spring is connected with the bracket plate; The top of the cable chamber door is provided with two pin holes, and the opening positions of the two pin holes correspond to the spring pin and the movable pin respectively.

In order to make the contact of the lower end of the movable bolt more flexible, the bottom end of the movable bolt described in the utility model has a hemispherical structure.

The operating principle of the utility model: when the cable in the cable room is in the working state of closing and electrification, close the door of the cable room, and the door of the cable room pushes the horizontal moving plate to move backward, at this time, the movable bolt falls and inserts into the door of the cable room under the action of its own gravity. The corresponding pin hole on the top, and then rotate the cam in the cam locking mechanism, the cam rotates and presses the spring pin to move down, and the lower end of the spring pin is inserted into another corresponding pin hole. Open; when the cable in the cable room is grounded, the cam in the cam locking mechanism rotates to another position, the spring latch pops up, the door of the cable room is not locked, and people can easily open the cable from the outside The chamber door can be operated without safety risk.

The utility model is ingeniously designed. When the ring main unit is charged (or the isolating switch is not grounded), the door of the cable room cannot be opened, which greatly improves the safety of high-voltage power supply and provides a strong guarantee for the personal safety of power supply personnel.

detailed description

Referring to Fig. 1 and Fig. 2, the utility model is a ring network cabinet with an anti-mis-opening device for a cable room, which has a cabinet body, and a circuit breaker mechanism operating room 1 is arranged on the upper part of the cabinet body, and a circuit breaker mechanism operating room is provided in the circuit breaker mechanism operating room. The circuit breaker mechanism 6, the lower part of the cabinet is provided with a cable chamber 9, the cable chamber door 5 is opened on the side wall of the cable chamber, a bracket plate 10 is provided on the side of the circuit breaker mechanism close to the cable chamber door, and a cam lock is arranged above the bracket plate Mechanism 2 is connected with a vertically downward spring latch 7 in contact with the cam 3 in the cam locking mechanism, and vertical guide rods 4 are arranged on both sides of the bracket plate, and a movable plate 13 is set on the vertical guide rods to move One side of the board is provided with a handle 14, and the bottom of the movable board is provided with a movable latch 8 vertically downward; a set of horizontal limiting device is provided below the bracket plate, and the lateral limiting device includes a laterally moving plate 12 and an extension spring 11, and the extension spring One end is connected with the laterally moving plate, and the other end of the extension spring is connected with the support plate; two latch holes 15 are provided on the top of the cable chamber door, and the opening positions of the two latch holes correspond to the spring latch and the movable latch respectively.

In order to make the contact of the lower end of the movable bolt more flexible, the bottom end of the movable bolt 8 in this embodiment has a hemispherical structure.

The operating principle of this utility model: see Fig. 5, when the cable in the cable room is in the working state of closing and electrification, close the cable room door 5, the cable room door pushes the transverse moving plate 12 to move backward, at this moment, the movable latch 8 is under its own gravity Insert it into the corresponding pin hole 15 on the top of the cable chamber door under action, then rotate the cam 3 in the cam locking mechanism 2, the cam rotates and presses the spring pin 7 to move down, and the lower end of the spring pin is inserted into another corresponding pin hole. The cable chamber door 5 is completely locked and cannot be opened from the outside; see Figure 3 and Figure 4, when the cable in the cable chamber 9 is in the grounded state, the cam in the cam locking mechanism rotates to another position at this time, and the spring When the latch 7 bounces up, the cable compartment door is not locked, and people can easily open the cable compartment door from the outside to operate without safety risk.

The utility model is ingeniously designed. When the ring main unit is charged (or the isolating switch is not grounded), the door of the cable room cannot be opened, which greatly improves the safety of high-voltage power supply and provides a strong guarantee for the personal safety of power supply personnel.
