Problems solved by technology

The general outdoor shielding box mainly focuses on the waterproof and dustproof function, but does not give too much consideration to the electromagnetic shielding function. Basically, it relies on the box material itself to achieve electromagnetic shielding, but such measures alone cannot achieve good results. Electromagnetic shielding effect

Embodiment Construction

[0032] The specific implementation manner of the present invention will be described in further detail below according to the accompanying drawings.

[0033] The invention provides a spark gap trigger control box for series compensation. The trigger control box includes a door frame support, a sealing rubber strip and a beryllium copper reed.

[0034] The door frame bracket is a bracket located on the four sides of the door frame to support the sealing rubber strip and the beryllium copper reed. The cross section of the door frame bracket is two L-shaped brackets ZJ1 and ZJ2 set in the back; the two L-shaped brackets ZJ1 and ZJ2 are The distance between the bottom edge and the door when it is closed is different. The L-shaped bracket ZJ1 on the side close to the door frame is far away from the door, and is fixedly provided with a sealing rubber strip that contacts the door when it is closed; the L-shaped bracket ZJ2 on the side far away from the door frame is far away from the ...

Abstract

The invention provides a spark gap trigger control box used for series compensation. The spark gap trigger control box comprises a door frame support, a seal rubber strip and a beryllium copper reed; the door frame support is a support which is located on four edges of a door frame and used for supporting the seal rubber strips and the beryllium copper reed, and the cross section of the door frame support is provided with an L-shaped support ZJ1 and an L-shaped support ZJ2 back to the L-shaped support ZJ1; the distance between the bottom edge of the L-shaped support ZJ1 and a box door is different from the distance between the bottom edge of the L-shaped support ZJ2 when the box is closed, the distance between the L-shaped support ZJ1 close to the door frame side and the box door is longer, and the seal rubber strip making contact with the box door when the box is closed is fixedly arranged on the L-shaped support ZJ1. The distance between the L-shaped support ZJ2 far away from the door frame side and the box door is shorter, and the beryllium copper reed making contact with the box door when the box is closed is fixedly arranged on the L-shaped support ZJ2. The spark gap trigger control box not only improves electromagnetic shielding performance, but also guarantees the good outdoor protective effect, and is simple in design, convenient to install, and reliable in function.

Description

technical field [0001] The invention relates to the field of a spark gap trigger control box, in particular to a spark gap trigger control box for series compensation. Background technique [0002] The spark gap for series compensation is the main protection of the voltage limiter (MOV) and the backup protection of the capacitor bank. As the key primary equipment of series compensation, the spark gap must have extremely high working reliability. A trigger control system is installed inside the spark gap trigger control box for series compensation. The series compensation protection system sends a trigger command to the system. After receiving this command, it sends a trigger pulse to the primary equipment to make the spark gap conduct, so that the voltage limiter and capacitor bank Bypass to avoid damage to the above equipment due to excessive fault current. At the same time, the trigger control system can also transmit its working status to the series compensation protect...
