Quick connector device for flexible medium-voltage cable

Abstract

The invention discloses a quick connector device for a flexible medium-voltage cable. The device comprises a middle socket and two cable terminal plugs, wherein one ends of the two cable terminal plugs are respectively connected to the ends of the two cables, and the other ends of the two cable terminal plugs are detachably connected to the two ends of the middle socket respectively. According tothe quick connector device, through the two cable terminal sockets and the middle socket, a standardized cable connector is achieved, and a connection between a ring main unit and the cable becomes very convenient and efficient; compared with a traditional copper pigtail connection mode, the connection speed of the connector device is increased by tens of times, a problem that the connection efficiency is low in the traditional mode is effectively solved, the on-site rapid connection is realized, the all-weather working environment is adapted, the efficiency of installation and power transmission can be effectively improved, a user complaint rate can be reduced, the connector is normalized, and the device adapts to connections of the cables of different manufacturers and is easy to installand convenient to match.

Description

technical field [0001] The invention relates to a quick plug joint device for flexible medium-voltage cables, belonging to the technical field of cable joints. Background technique [0002] The construction personnel directly install the cable accessories on the ring network cabinet. Due to the different manufacturers of the ring network cabinet, the shape and accessories of the switch cabinet are various, and the requirements for the length of the cable exploitation and the fixing method are inconsistent. As a result, the construction personnel must understand the switchgear or install it under the guidance of the equipment manufacturer, resulting in Long installation time; the weather at the installation site is changeable. In rainy weather, if the ring main unit is installed forcibly, it will bring safety hazards to the construction personnel and equipment operation. [0003] At present, the cable accessories installed in China mainly use the "T-shaped head" and "copper n...

Problems solved by technology

[0002] The construction personnel directly install the cable accessories on the ring network cabinet. Due to the different manufacturers of the ring network cabinet, the shape and accessories of the switch cabinet are various, and the requirements for the length of the cable exploitation and the fixing method are inconsistent. As a result, the construction personnel must understand the switchgear or install it under the guidance of the equipment manufacturer, resulting in Long installation time; the weather at the installation site is changeable. In rainy weather, if the ring network cabinet is installed forcibly, it will bring safety hazards to the construction personnel and equipment operation

[0003] At present, the cable accessories installed in China mainly use the "T-shaped head" and "copper nose" connection scheme. This scheme has a long history. On the one hand, the processing accuracy of "copper nose" is not high, and the requirements for equipment and materials are low. In addition, most of the accessories are Ruth, nuts, gaskets, etc., which look simple and uncomplicated. The tools are relatively common wrenches, crimping pliers, etc., so they have been used in many industries, and the power supply industry is no exception. Copper noses are only suitable for fixed connections, such as manufacturing process and installation problems, which will lead to rough contact surfaces, unreliable connections, and electrical performance problems such as heat generation. In addition, there are many cable accessories manufacturers and styles, which often make copper noses difficult to install and match. and other problems, making it difficult to implement the cable installation work

The T-shaped head is installed outside the "copper nose", so that the construction personnel cannot visually see the connection of the "copper nose", and cannot guarantee reliable contact with the ring network cabinet
