Description

Set the switchgear of the plug-in high-voltage live display

technical field

The invention relates to a switch cabinet provided with a plug-in high-voltage live display.

Background technique

At present, most of the high-voltage live monitors on the market are used in 10kV and 35kV indoor switch cabinets, and the high-voltage live monitors are installed on the cabinet doors of the switch cabinets. During installation, holes need to be drilled on the cabinet door of the switch cabinet. Because the commonly used live monitors are divided into two types according to the size, there are also two types of opening sizes for the corresponding switch cabinet doors: the largest opening size is 92 (±1)×44 (±1) mm; The size of the small opening is 100 (± 2) × 70 (± 2) mm.

According to the structure, the high-voltage live display on the market is mainly divided into two types: one is an integrated high-voltage live display; the other is a plug-in high-voltage live display. For the switchgear with integrated high-voltage live display, the display must be replaced after power failure. However, if the plug-in high-voltage live display is used, it does not need to be replaced after power failure. Therefore, from the perspective of maintenance, the plug-in live display is more superior than the integrated type.

At present, most of the openings on the door of the switchgear used in the power system are large-sized openings, and an integrated high-voltage live display is used, which often causes power outages due to the replacement of the high-voltage live display. However, the plug-in high-voltage live monitors on the market are all small in size and cannot be directly applied to the switch cabinets used in the current power system. Therefore, it is impossible to maintain the high-voltage live monitors without power failure.

The technical scheme adopted by the present invention to solve the problems of the prior art is: a switchgear with a plug-in high-voltage live display, including a switchgear body, a cabinet door arranged on the cabinet body, and a plug-in high-voltage switchgear arranged on the cabinet door The charged display is characterized in that the display is arranged in the third installation cavity of the cabinet door through an adapter, and the adapter includes a first adapter plate, a second adapter plate and a fastening assembly, and the first There is a first installation cavity on the adapter plate, and a second installation cavity on the second adapter plate, and the display passes through the first installation cavity, the third installation cavity and the second installation cavity in sequence and is positioned by the fastening assembly on the cabinet door. An adapter device is added to make the plug-in high-voltage live display suitable for the switchgear used in the current power system, and realize the installation of a small plug-in high-voltage live display on the cabinet door with large openings, which is convenient for maintenance personnel to replace the high-voltage live display with live Display, prevent maintenance personnel from electric shock and equipment damage, ensure personal and equipment safety, improve power supply reliability, and reduce or avoid the impact on social electricity consumption. At the same time, the small plug-in high-voltage live display is applied to the switch cabinet with a large opening to realize the interchangeability of the plug-in high-voltage live display and the integrated high-voltage live display. In the case of lack of spare parts, you can choose the stocking one The plug-in high-voltage live display or integrated high-voltage live display brings great convenience to the maintenance work and avoids the phenomenon of inoperability due to lack of spare parts.

As a further improvement and supplement to the above technical solution, the present invention adopts the following technical measures: the outer wall of the display is provided with a fastening groove, and the fastening component includes a hook and a hook through the hook to connect the hook to the cabinet door. As for the connecting part, an outer convex buckle is provided on the outer side of the hook, and the outer convex buckle is buckled and matched with the fastening groove. The hook hanger hooks the display, and the display is fixed on the cabinet door through the connecting piece.

In order to make it more reliable to fix the display on the cabinet door, the corresponding two sides of the outer wall of the display are provided with the fastening grooves, and each side of the fastening grooves is respectively provided with a set of fastening components. There are at least two fastening grooves at intervals, and the fastening grooves on the same side are arranged on the same straight line. The arrangement of the convex buckles on each set of hooks corresponds to the arrangement of the fastening grooves.

In order to avoid displacement of the first adapter plate relative to the cabinet door, the first adapter plate is provided with a snap-in boss and an overlapping edge arranged on the outer edge of the snap-in boss, and the snap-in boss is embedded in the third mounting chamber.

The inner edge of the clamping boss is flush with the side wall of the first installation cavity, and the outer edge is closely matched with the side wall of the third installation cavity.

The thickness of the clamping boss is greater than the thickness of the overlapping edge. The setting of the clamping boss is used to avoid displacement of the first adapter plate relative to the cabinet door on the one hand, and to increase the thickness and strength on the other hand.

The present invention has outstanding substantive features and significant progress: 1. An adapter device is added to make the plug-in high-voltage live display suitable for the switchgear used in the current power system, to realize non-stop maintenance of high-voltage live display, reduce or avoid Impact on social electricity consumption. 2. Realize the interchangeability of the plug-in high-voltage live display and the integrated high-voltage live display, so as to avoid the malfunction caused by the shortage of goods. 3. The structure of the transfer device is ingenious and simple, which is convenient for production, processing and installation. At the same time, the plug-in high-voltage live display is stable and reliable, easy to disassemble and assemble, and realizes non-stop operation.
