What is a plug-in?

What is a plug-in?

Primary connector mainly refers to the connector used on the primary line (i.e. the main line) in the distribution cabinet, which completes the circuit conduction through the dynamic and static plug-ins. Connectors (contacts) are the core parts of the connector to complete the electrical connection function. Generally, the contact pair is composed of a positive contact and a negative contact, and the electrical connection is completed by inserting and closing the negative and positive contacts. The corresponding current is determined according to different cabinet types and circuits, and the general voltage is 380V, 660V or higher. The current is divided into 160A, 250A, 400A and 630A. The highest is 630A (theoretically speaking, generally not). Corresponding to the primary connector, there are secondary connectors, which are mainly used for the secondary control circuit in the distribution cabinet. The functions are the same, the places used are different, and the corresponding current and voltage are lower. Generally, the voltage used in industry is AC 220 V or DC 110 v.

Contribute wisdom to the global economy to achieve green development

Contribute wisdom to the global economy to achieve green development

Under my country’s initiative, green finance issues were included in the G20 agenda for the first time this year, and a green finance research group was established and the G20 green finance comprehensive report was launched. In this report, the definition, purpose and scope of green finance, and the challenges it faces are clarified, and suggestions are made for the development of green finance in various countries to support global sustainable development.

China’s fire emergency lighting industry is gradually switching to an intelligent evacuation indication system

China’s fire emergency lighting industry is gradually switching to an intelligent evacuation indication system

From the traditional emergency lighting indicator, to the UPS power supply for centralized power supply emergency lighting, and then to the EPS emergency power supply (or FEPS power supply) for centralized power supply emergency lighting, they only reflect the protection function on the power supply backup power supply, and in the terminal lighting group There are deficiencies in interactive self-control and humanized design. The rise of the intelligent evacuation indicator system has made up for the shortcomings of previous products, and truly embodies the advantages of green, energy-saving, safe and reliable fire emergency lighting and indicator evacuation. The intelligent evacuation indication system is currently and will surely be the mainstream product dominating the industry in the future. EPS emergency power supply (or FEPS power supply) will only retain a certain small market share in special applications in the future (about 20% of emergency lighting places for gas discharge lamps such as high-brightness high-pressure sodium lamps).

The national fire-fighting electrical industry is gradually strengthening and improving the post-event supervision function

The national fire-fighting electrical industry is gradually strengthening and improving the post-event supervision function

In the past, the supervision and random inspection of fire products by the national fire monitoring agency was generally limited to the manufacturer’s production sites and warehouses. But now, the main manifestation of spot-checked products is shifting to the subject matter operated on site by users, and the monitoring is becoming stricter, and the product flow registration system has become a killer tool for suppressing counterfeit manufacturers.

Primary connector refers to the connector used on primary line (i.e. main line) in distribution cabinet, and the circuit is connected through plug-in of dynamic and static plug-in. Contacts is the core part of the connector to complete the electrical connection function. Generally, the contact pair is composed of positive contact and negative contact, and the electrical connection is completed by the plug-in of the female and positive contacts. The corresponding current is determined by different cabinet types and circuits, and the general voltage is 380V, 660V or higher. The current is divided into 160A, 250A, 400A, 630A. Up to 630A (theoretically, it is generally not). For the primary connector, there are secondary connectors. It is mainly used for secondary control circuit in distribution cabinet. The function is the same, the place used is different, the corresponding current is small and the voltage is low. Generally, the voltage used in industry is AC 220V or DC 110V.

Insulators can be divided into low-voltage insulators and high-voltage insulators according to different voltage levels. High voltage insulator refers to the insulator used in high-voltage and ultra-high voltage overhead transmission lines and substations. In order to meet the needs of different voltage levels, different numbers of single (piece) insulators of the same type are usually used to form insulator strings or multi section insulation pillars.
