The air switch is divided into the upper inlet line and the lower inlet line of the power supply, 1 is - 3 is + 2 is + 4 is - when the upper line is inlet, 2 is + 4 is - This is related to the internal trip curve.
DC circuit breaker: used for DC system operation method conversion or fault removal. Such as metal return conversion circuit breaker (MRTB), earth return transfer switch (GRTS). Discipline of use: Electricity; The transformer tap-changer voltage regulation method of high-voltage DC transmission load regulation refers to the difference in that the non-excitation voltage regulator switch does not have the ability to bring load conversion gear, because this tap-changer has a short-term disconnection process in the process of conversion gear, and the disconnection load current will cause the arc between the contacts to burn out the tap-changer or short circuit, so it is necessary to make the transformer power out when adjusting the gear.
It is generally used for transformers that are not very strict in voltage requirements and do not need to be adjusted frequently. The on-load tap-changer can switch gears with load, because the on-load tap-changer does not have a short-term disconnection process in the process of shifting, and transitions from one gear to another gear through a transition resistor, so that there is no arcing process of load current disconnection.
DC circuit breaker DZ47-63Z/1P has a first-class current limiting function, which can accurately maintain relay maintenance and automatic devices from overload, short circuit and other faults.
DC circuit breaker DZ47-63Z/1P adopts a special arc extinguishing to quickly break the faulty current of the DC distribution system, so that the gradation coordination has been greatly improved. DC circuit breaker DZ47-63Z/1P especially for the power engineering DC system between the test and protection screen and the distribution screen presented by the tripping and other incidents, small DC circuit breaker DZ47-63Z/1P series has excellent functions, can prevent the above problems.
