Problems solved by technology

However, in actual installation, it is difficult to achieve flushing on both sides after fixing using this technology for positioning
In this case, there is a gap at the busbar connection and there is a potential creepage; in addition, the connecting busbar is always under stress, which will cause poor contact, and there are potential safety hazards in long-term operation.

Embodiment Construction

[0026] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0027] like Figure 1 to Figure 4 As shown, the present invention includes a first side panel 1 and a second side panel 2 connected to each other when combining cabinets. The first side panel 1 and the second side panel 2 are respectively arranged on opposite sides of the ring network cabinet, that is, the left and right sides , the first side plate 1 and the second side plate 2 are provided with a threading hole group 4 consisting of at least two threading holes 3 for passing through the busbar. Usually, a general ring network cabinet will be provided with three threading holes 3 to Corresponding to the arrangement of the bus bars, the threading hole group 4 is composed of three threading holes. It is characterized in that: the threading hole group 4 is symmetrically provided with the raised positioning head 5 and the raised positioning hole 6 in the opposi...

Abstract

The invention relates to a ring main unit jointing and locating structure. The ring main unit jointing and locating structure comprises a first lateral plate and a second lateral plate, which are mutually connected in a jointing process; both the first lateral plate and the second lateral plate are each provided with a threading hole set composed of at least two threading holes; a protrusion type locating head and a protrusion type locating hole are symmetrically arranged on the threading hole set in the relative direction; and the connection line between the centre point of the protrusion type locating head and the centre point of the protrusion type locating hole passes through the centre point of the threading hole set. The locating structure is additionally arranged on a stainless steel gas tank shell encapsulation plate of a standard ring main unit; the locating structure is symmetrically installed near a bus connection position; and thus, the fact that a bus connector is reliable to contact in an installation process, and difficultly influenced by external force can be ensured.

Description

technical field [0001] The invention relates to the technical field of electrical cabinet products, in particular to a positioning structure for ring network cabinets. Background technique [0002] The ring main unit is a kind of air-insulated or gas-insulated fully insulated medium-voltage electrical combination equipment that can be combined into multiple circuits at will. It is generally composed of standard units (or combination units) through flexible expansion and combination to meet power distribution needs. At present, the mainstream ring network cabinets in the market adopt fully sealed and fully insulated technology. Therefore, during the combined installation process of multiple ring network cabinets, the insulated busbars should be as accurately aligned as possible without large deviations. Now generally design multiple installation holes on the left and right side panels of the installation cabinet body, and play the role of fixing and positioning at the same ti...
