12kv Quik-Lock Plugs and Receptacles for Medium Voltage

Product Description

General Information

Medium-voltage emergency power supply quick-plug interface, also called emergency power supply quick-connect coupler, or medium-voltage quick-plug connector. One end of it is connected and fixed with the connector on the generator car, and the other end is connected and fixed with the emergency power interface on the medium-voltage switch cabinet to form an emergency power supply quick access system. Widely used in power generation vehicles, generators, distribution cabinets, power distribution, etc. Products are divided into two voltage levels: medium voltage and low voltage.

Emergency power generation vehicle is a kind of emergency backup power generation equipment, which is usually used to provide power when there is a sudden power outage or the site cannot be connected to the power grid. Emergency power generation vehicles are mainly used in the following scenarios: First, there is a sudden power outage or the site cannot be connected to the power grid. For example, in the case of a power outage or the site cannot be connected to the power grid due to natural disasters, facility failures, line or equipment maintenance, etc., emergency power generation is required. The car can provide power supply service as a backup power source. The second is temporary energy demand, such as construction, performance and other projects. In the case of temporary energy demand, emergency power generation vehicles can provide the required power output capacity to meet temporary energy demand. The third is the demand for mobile power supply. Due to its high mobility, it can facilitate power supply and emergency response where needed.

In China, currently, power generation vehicles are mainly divided into 10kV medium-voltage power generation vehicles and 0.4kV low-voltage power generation vehicles. Medium voltage mainly generates electricity through 10kV high-power generator vehicles, providing temporary emergency and reliable power supply services to important local high-power users. Medium-voltage power input methods include overhead lines to overhead lines, overhead lines to ring network cabinets, ring network cabinets to ring network cabinets, 10kV lines to 0.4kV lines through mobile boxes and other bypass methods. The application range of low-voltage grid-connected generator cars will be wider and can be connected to wall-mounted, floor-standing or embedded switch cabinets.

According to the requirements of the standardized design of distribution network equipment of the State Grid of China, PT node switches need to be equipped with emergency bushing interfaces for 10kV generator docking.

Product Features

1. The conductor adopts plug-in structure and is easy to install. Small size, quick connection, simple operation and convenient connection.
2. This product is safe and reliable, and there is no spark when plugging or unplugging. The connector adopts a connection system with a locking mechanism, which is firmly connected and has the function of preventing electric shock.
3. The quick connector has strong current carrying capacity, extremely small contact resistance, reliable contact, can pass large currents and generates very little heat (the core technology of elastic contact finger multi-point contact principle has long been widely used in multinational high-voltage switchgear such as Siemens. Has reliable contact and minimal temperature rise issues).
4. The insulation is connected by cold shrinkable silicone rubber, which has good insulation performance.
5. Using aluminum alloy shell, the product has strong impact resistance.
6. Mechanical life: The panel socket coupler can be plugged and unplugged not less than 5,000 times in the correct plugging and unplugging method.
7. The product is waterproof, fireproof, salt spray and corrosion resistant (applicable to ports), cold-resistant, high-temperature resistant, aging-resistant, suitable for harsh environments, and has a long service life.
8. Maintenance-free, energy-saving and environmentally friendly.

Scope of Application

In addition to emergency power connections, this product is also used in outdoor bypass switches for non-power outage maintenance. In addition, this product is also widely used in harsh field operations and highly polluted flammable and explosive places; used for the connection of shield machine construction cables in subway tunnels, irrigation canal tunnels, air defense tunnels and other shield machine construction cables.

SF6 Gas Insulated Switchgear Emergency Power Fast Socket

 

 

In order to meet the need of emergency power supply in outdoor field operation, an integrated node switch and a power supply interface are arranged in the PT unit cabinet of the outdoor SF6 GIS ring net box. When the power-taking interface is idle, it needs to be blocked by the plug of the integrated node, and when the power-taking interface needs to be plugged, it only needs to take out the plug and insert the power-taking plug into the interface to be fixed with a rotating snap, after the power will be installed plug for the next power use.

This product is used for SF6 GIS switchgear cabinet emergency power supply quick access. Product implementation standards: IEC 60502, GB/T12706,GB/T11022. Product matches EN50180-50181medium a casing. Thee recommended size of air box hole is202 casing standard hole, recommended for 735mm. Fully shielded, fully insulated, fully sealed connection. The base is pressing plate without additional pressing plate.
