Introduction to the ground plug, what are the advantages and disadvantages of the ground socket?

In the office or home decoration, everyone often sees the ground insertion. Compared with other sockets, the ground insertion is convenient and convenient, and the space occupied is small and the appearance is beautiful. The following small series will introduce the advantages and disadvantages of the ground insertion. To help you better understand the ground socket.

First, the introduction of the ground socket

Floor socket, referred to as: ground plug. Full name: ground socket for household and similar purposes. A socket that is installed on the ground or the like for connection to a fixed wiring, and is usually used as a terminal and an outlet of a ground wiring system to take out power, signals, and data in the ground wiring system. It is mainly used in office spaces, airports, hotels, shopping malls, homes, etc., and is widely used.

Second, the advantages of the ground socket

1. Has strong surface corrosion resistance requirements.

Due to the complicated use environment and often subject to strong friction, the surface protective layer of the product is required to have strong corrosion resistance, wear resistance and oxidation resistance.

2. Easy to install. Adapt to different construction environments, different structures and thickness of the floor requirements. The ground socket should be easily docked with the pipe socket of the ground wiring system.

3. Easy to use and safe . The product can be easily opened or closed for easy use, and the opening or closing state does not significantly hinder the movement or movement of people or objects in the building. And should be able to clean the floor cleaning. The ground sockets should have different levels of protection to suit the different requirements of the environment to ensure the safe use of users. The degree of protection for dry-handled floor sockets is usually IP20 and that of wet-treated floor sockets is IP44. Special circumstances will have higher requirements.

4. Beautiful appearance . The appearance and shape are coordinated with the floor and integrated into one. In recent years, there have been many ground sockets specially equipped with marble floors, carpet floors and floor rubber floors.

We offer you various types of ground sockets for you to choose. Siemens switch socket panel is made of five-hole copper alloy, and the shell is made of copper alloy. It has high strength, durability and beautiful appearance. The cover is inlaid with a waterproof sealing ring, which has a high waterproof and dustproof rating, so that the liquid of the water droplet is not easy to enter.

Third, the ground socket shortcomings

1. The variety of socket ports is single . Due to the development of computer and communication technology, modern intelligent buildings have more and more requirements for the variety of ground terminal sockets. However, the current sockets have fewer types of sockets, and because they are generally not interchangeable, they limit the use range of the ground sockets.

2. The product application range is small. In modern buildings, the ground socket should have basic functions such as power supply, computer and communication. At present, the above requirements can only be partially met on a ground socket.

3. The product structure is unreasonable. In the working state, since the pop-up and clamshell sockets need to eject or flip the port of the socket, it is easy to kick or kick the plug, which is neither safe nor beautiful; and the cap-type upper cover is in working state. Easy to lose.

4. The degree of protection is low. According to China's national conditions, the requirements for dustproof and waterproof of smart building ground sockets are high. The plugs and sockets of the above products are exposed when working, so the degree of protection is generally low.

5. The product cost is high. At present, most of these domestic socket products are made of non-ferrous materials, so the material cost is high.

The above is some of the contents of the small series for everyone to insert, including the advantages and disadvantages of the ground insertion, etc., want to know more about the knowledge of the ground insertion, please continue to pay attention to the sale of treasure encyclopedia channel.

MPPT Controller

A solar Controller is an electronic device that controls the circulating pump in a solar hot water system to harvest as much heat as possible from the solar panels and protect the system from overheating.

Two kinds solar controller included:

1.PWM Controller

2.MPPT Controller


MPPT stands for Maximum Power Point Tracking. MPPT is a technique to observe and regulates the energy going from Solar Panel to the batteries. Solar panels show changeable outputs according to weather conditions. MPPT charge control devices can match the solar panel voltage with Battery voltage to maximize the charge efficiency. In these systems, the full power of solar panels can be used by balancing between voltage and current according to the P = V x A equation. For example, the amount of current drawn from the panels reduced to protect the voltage when the weather is cloudy. When the weather is sunny, it is allowed to draw more current.


The main difference between PWM and MPPT charge control devices is that the MPPT devices are more efficient. MPPT charge control devices have 30 % more efficient in charge efficiency according to PWM type. Panel voltage and battery voltage should be matched in PWM systems. In MPPT systems, the panel series are allowed to have higher voltage than batteries. This means more flexibility for system growth.
