Distribution Box : Distribution box is used to split the power distribution and installation of air box switch box, the distribution box is generally made of metal, the front panel with plastic and metal, the panel also has a small flip cover to facilitate Open, the small clamshell covered with a transparent and opaque distribution box specifications according to the inside of the branch, small four, five, more than a dozen, before choosing the distribution box, we must first design Circuit shunt, and then open according to the number of open, and whether it is a single open or double open, calculate the specifications of the power distribution box generally occupy the distribution box where there should be wealthy, in order to increase the circuit later
Circuit breakers , full automatic air circuit breakers, also known as air switch, is a commonly used low-voltage electrical appliances, can achieve short circuit, overload protection and other functions
Circuit breakers for home power supply for the main power protection switch or branch line protection switch when residential lines or household appliances in the event of a short circuit or overload, it can automatically trip, cut off the power, thus effectively protecting these devices from damage or prevent the accident to expand
Families generally use the diode (ie 2P) circuit breaker for the total power protection, with a single pole (1P) for branch protection
If the rated current of the circuit breaker is too small, the circuit breaker will easily trip frequently, causing unnecessary power failure. If the choice is too large, the expected protection effect will not be achieved. Therefore, the proper selection of the rated capacity and current capacity important
General specifications of small circuit breakers are mainly divided by rated current 6A, 10A, 16A, 20A, 25A, 32A, 40A, 50A, 63A, 80A, 100A, etc.
What is the distribution box with the total power does not matter but the circuit and the circuit number is related to the distribution box bought back then with the air switch (referred to as open) and leakage protection (referred to as leakage protection) as to how much you can use Depends on the power you want to enter the line rated current bus and socket on the general open to install leakage protection (or with leakage insurance open)
Leakage protector 30mA: is the general operating current leakage protection switch, usually people have a sense of electric shock current and get rid of the current, meaning that when the current value reaches a certain point after people get numb, this time the human brain is still conscious, Can control themselves to get rid of electric shock When the electric current and then large to a certain value, people can not control themselves get rid of electric shock, and have been unconscious, the current value is 30mA so the leakage current protection switch is set to 30mA current leakage standards are 30 mA, that is, if the leakage current is greater than 30 mA trip action
Inside the open and the number of leaks according to your circuit to determine when to buy the distribution box as long as the circuit board to tell how many loops on it
However, the circuit breaker has no obvious indication function of the line breaking status or the closing status (that is, the operation status that the operation staff can see). Therefore, a knife switch such as a knife switch should be added in front of the automatic circuit breaker (power supply side) Not used to break and close the line current, commonly known as the isolation switch
Weak electrical box: Weak electrical box is designed for home weak wiring system, also known as smart home wiring boxes, multimedia boxes, residential information wiring box on the family of broadband, telephone lines, audio cable, coaxial cable, Security network and other lines for a reasonable and effective layout to achieve people on the phone, fax, computers, audio, TV, DVD players, security monitoring equipment and other network information appliances centralized management and sharing of resources is to provide home wiring system Solutions for the product
Power distribution box to solve the problem of electricity safety, and low-voltage junction box to solve the problem of unobstructed information, weak box to facilitate the management and maintenance of weak, on-demand adjustment of each line and management, and to expand the use of functions, so that the family weak Reasonable distribution of lines, unobstructed information, such as failure, easy to check and maintain
Weak box of active equipment broadband routers, telephone switches, cable signal amplifier, the structure of a modular (active device is a manufacturer-specific integrated module) and finished (active equipment is the use of existing manufacturers of finished equipment ) In contrast, both finished products of active equipment to buy the mature brand on the market, the quality is relatively stable and reliable, more advanced technology, affordable, easy to replace and repair in the future
Passive equipment in the weak box can use the supporting module (such as cable module, telephone distribution module, etc.) produced by the weak box manufacturer to keep the inside of the box clean and tidy. Source equipment, and configure the power outlet, but also for future upgrades In the cabling, in addition to laying power lines, there are laid cable TV and telephone lines, audio lines, video lines and network lines in addition to these lines are called power cables For the "weak", the transmission of a variety of signals, we want to build a multi-functional, modern, intelligent home environment indispensable This is the necessary wiring Poor wiring cabling requires professional engineers to make comprehensive and rational planning and design for the owners And construction, the only way to make the overall decoration beautiful, orderly, practical, easy to use now and future expansion.
