Many people don't know what a surge is, surge is also known as power surge or lightning protection maintainer, the first is to maintain the household electrical equipment when it rains and thunders to avoid being damaged by lightning, when lightning strikes high-voltage electricity is drained to the ground through the surge maintainer, it will not directly hit the electrical equipment.
1. What is a surge maintainer?
Answer: Delixi's surge maintainer is an electronic component, when the circuit or communication line due to lightning strike high current suddenly peak current or overvoltage, can be instantaneously shunted to guide the high current voltage to the ground, so as to avoid surge damage to other equipment in the circuit.
2. What types of surge maintainers does Delixi have?
Answer: Delixi's current models are: DZ47Y surge, CDY1 surge has been discontinued, CDY6 surge and CDY9 surge
3. Why does Delixi surge have switch type and voltage limiting type, and what is the difference between the two?
Answer: Delixi's surge maintenance is a void discharge device, its lightning shock discharge capacity is large, its primary function is online discharge lightning energy; The voltage limiting surge maintainer is a zinc oxide varistor device, which has a small lightning energy discharge ability, but has a good overvoltage suppression ability, and its primary function is to confine the overvoltage online. Therefore, a switch-type surge maintainer is generally selected at the entrance of the building to release the lightning energy, and then the voltage-limiting surge maintainer is used in the post-stage circuit to restrain the high overvoltage that occurs in the post-line after the lightning energy is released in the previous stage. It is best to use T1 and T2 surge maintainers together to maximize the safety of the equipment in the distribution line.
4. Do I need to install a fuse and circuit breaker in front of the surge maintainer?
A: It can be installed or not. The purpose of the front fuse and circuit breaker is to avoid damage to the SPD and its line due to the power frequency freewheeling caused by lightning strikes, and it can also facilitate the repair and replacement of surges.
5. How many levels of Delixi surge are there, and what are the differences?
Answer: There are 2 levels of Delixi surge, which are T1 and T2 levels. The main differences are: the current capacity of the T1 surge maintainer is large, the discharge current is generally 100-200kA, and the voltage maintenance scale is 1800-2000kV; The discharge current of the T2 surge maintainer is 20-80kA, and the voltage maintenance level is less than 2500kV. The surge maintainer of T1 is mainly used for the discharge of lightning current, and the product curve is mainly 10/350μs wave type; The primary function of the T2 surge maintainer is to constrain the overcurrent voltage, and the product curve is an 8/20μs wavepattern.

Methods for preventing breakdown of transformer insulation
1. Avoid water and air entering the transformer
(1) The transformer should be protected from water ingress and moisture during operation, and it is necessary to seal well the cap of the casing item, the top of the storage phase, the bushing pipe and its connecting pipes. If necessary, a leak detection test should be carried out, and if the insulation has been found to be damp, it should be adopted in time.
