Overview
● Install high-voltage capacitors at both ends of the 304 stainless steel shell of the circuit breaker to take power, and adopt a double-sided power supply mode tointegrate the design of the circuit breaker and the shell. The power-taking capacitor is not affected by weather and load current changes, and is stable and reliable.◎ The integrated design of circuit breaker + power-taking capacitor + intelligent measurement and control terminal realizes information collection and remotecontrol.
● The integrated design of intelligent measurement and control terminal and capacitor power-taking circuit breaker can be combined in the single-sidepower-taking capacitor and double-side power-taking capacitor electromagnetic transformer. The specific configuration is: power supply voltage transformer +current transformer + zero-sequence voltage sensor voltage The specific configuration of the combined analog output mode of /current sensor is: power supplyvoltage transformer (or capacitor power-taking module) +voltage sensor + current sensor, and the specific configuration of the combined digital output mode ofvoltage/current sensor is: power supply voltage transformer +voltage sensor +Current sensor+Sensor digital unit,parameter setting and remote control.
● The integrated capacitor circuit breaker is convenient for on-site installation and prevents on-site wiring errors.
Product Features
● Advanced technology, practical and simple: Based on directional soG technology, small current and voltage sensing signals and phase detection technology canaccurately determine small current grounding and disconnection faults, effectively preventing fires in mountains, forests and grasslands,and grounding faults thatwill affect the safe operation ofpersonal equipmentACCIDENT.
● Highly integrated and safe operation: Adoptinternational standard solid-sealing technology to integrate vacuum interrupter, current sensor and voltage sensor as awhole, without after-installed components, each phase pole <5pc, and the whole machine is no more than 20pcb.
● A variety of sensing signals are complete: the voltage on both sides of the power supply side and the load side can be integrated, zero-sequence voltage sampling,and 8U41independent component sampling can meet the accuracy requirements and various application requirements.Self-contained power supply for energy saving and consumption reduction: It can realize the configuration oflow-power FTU and standardized FTU combined with theflexible internal and external capacitor power supply scheme of the switch body and the standardized scheme, which can meet various schemes in different markets.
● The whole pole casting is reliable and beautiful: the beautiful appearance design also takes into account the high altitude, which can meet various altitudes and live
installation. The same appearance can be applied as a 24kv power distribution system.power distribution system.
