KM-FTB large capacity explosion-proof overvoltage protector


Product Brief

Large-capacity explosion-proof overvoltage protector, referred to as KM-FTB, is designed to overcome the disadvantage of conventionally combined overvoltage protector, which may lead to a serious reduction of product life and unexpected thermal burst when facing the resonance overvoltage of the system. Compared with the conventionally combined overvoltage protector, the device adds the functions of automatic disconnection, resistance, and capacitance absorption, and solves the problems of repeated burning caused by high-frequency oscillation and slow response of zinc oxide to high-frequency overvoltage signal, which can not protect the vacuum circuit breaker. Structurally, the device will be large-capacity high-energy zinc oxide valve sheet (800A/2ms), resistance-capacitance absorber, disconnector, and silicone rubber insulation sheath integral film forming, the protector sealing performance greatly improved. The device also has the functions of overvoltage action counting, fault detached indication and long-distance data transmission. The operation is free of maintenance and solves the user's concerns about the safe operation of the system.

Product application

The large-capacity explosion-proof overvoltage protector KM-FTB has perfect protection function depending on its many advantages. It can reliably limit the atmospheric overvoltage, the interruption overvoltage caused by the vacuum circuit breaker interruption and various switching overvoltages, as well as the phase-to-phase and relative ground overvoltages. Mainly used in power generation, power supply and enterprise power systems, used to protect electric motors, transformers, switches, buses, capacitors and other electrical equipment. And because of the use of large capacity and high-energy zinc oxide valve sheet, more suitable for some over-voltage limit effect requirements higher occasions, is an ideal device for over-voltage protection products.

Product characteristics

High-capacity explosion-proof overvoltage protector KM-FTB retains the four-star connection method of conventionally combined protector. High-capacity and high-energy zinc oxide valve sheet is used to replace the ordinary zinc oxide valve sheet. Detachment and resistance-capacitance absorber are added, and integral pressure film is adopted in structure. The product has the following functions:

The energy can reach 800A/2ms by using high energy capacitance zinc oxide nonlinear resistor, which has large current capacity and wide application range. Especially in some places where the insulation of the protective equipment is relatively weak, which are prone to over-voltage for a long time.

The problem of repeated burning of vacuum circuit breaker caused by high-frequency oscillation and the problem of slow response of zinc oxide to high-frequency over-voltage signal and no protective effect was solved by adopting the structure of resistance-capacitance absorber and high energy zinc oxide valve sheet.

As a result of the use of off-function, the device itself has been protected to solve the user's worries about the safe operation of the system.

Overvoltage counting and real-time monitoring functions are added to facilitate users to understand the status of the system overvoltage and provide a guarantee for analyzing the system causes and preventing accidents.

The structure is made of an integral pressing film with better sealing performance.
