Switching components
There are three types of switching components: ceramic gas discharge tube, glass discharge tube (strong discharge tube), and semiconductor overvoltage protector (semiconductor discharge tube, solid discharge tube). Their advantages are: ①Before breakdown (conduction), it is equivalent to an open circuit, with a large resistance and almost no leakage current; ②After breakdown (conduction), it is equivalent to a short circuit, which can pass a large current with a small voltage drop; ③The pulse current capacity (peak current) is large: the 8/20μs wave peak current of the ceramic gas discharge tube is commonly used in 5kA, 10kA, 20kA, etc. (of course there are larger ones, up to 100kA or more), 10/1000μs wave The peak current is between tens to hundreds of A; the 8/20μs wave peak current of the glass discharge tube is currently 500A, 1kA, and 3kA; the 10/1000μs wave peak current of the semiconductor overvoltage protector is between tens to hundreds of A between. ④ Except for individual semiconductor overvoltage protectors, they all have two-way symmetry. ⑤The capacitance of ceramic gas discharge tube and glass discharge tube is very small, below 3pF. ⑥The response speed of the glass discharge tube and the semiconductor overvoltage protector is very fast, in the order of ns. ⑦The breakdown voltage of the glass discharge tube can be made very high, up to 5kV. ⑧The breakdown voltage of the semiconductor overvoltage protector can be made very accurate.
Anti-overcurrent and overheating protection components
The anti-overcurrent components have self-recovery fuses, current fuses, and resistors, and the anti-overheat protection and overheat detection components have temperature fuse and temperature fuse. A resettable fuse is a positive temperature coefficient thermistor. When the current flowing through it is less than its holding current (low temperature), its resistance is very small; when the current flowing through it exceeds its trigger current (temperature Increase), its resistance value increases sharply, thereby blocking the continuous intrusion of lightning current or the freewheeling of the circuit, and it can recover by itself after the temperature drops. However, due to thermal inertia, the reaction speed is very slow, generally in seconds (the greater the current or the higher the temperature, the faster the reaction). Self-recovery fuses can be used to replace current fuses, eliminating the trouble of frequent replacement. Thermal fuse and thermal fuse are a kind of temperature switch components, which are short-circuited during normal operation. When the temperature is higher than the disconnection temperature, the switch will be disconnected (unrecoverable). They are often used for overheating protection and overheating detection.
Shell material:
Using international brand nylon material and international brand PBT material, the bending strength is in accordance with GB/T9341-2008, and the impact strength of the simply supported beam is notched and unnotched. Comply with GB/T1043.1-2008, flame retardancy complies with GB/T2408-2008, excellent electrical insulation performance, and strong consistency of product surface technology.
Stamping:
It is made of high-precision copper, and the screws and locking sleeves are electroplated after heat treatment. The advantage is that the product is not easy to slip, the salt spray test can reach 72 hours, and the plugging force is moderate.
Elaboration
1. It is recommended that the maximum flow of SPD Imax: 10-60KA.
2. It is recommended that SPD be used in an environment of -40℃ to +100℃.
3. 1P, 2P, 3P, 4P can be distributed according to demand to meet various needs.
4.35mm guide rail design is convenient for subsequent installation.
