Specifications
The circuit breaker be superior to domestic like products. It is the first choice of 550KV power system;
General:
LW30-550(T)/Y5000-63 high voltage SF6 tank-type circuit breaker is invented by our company so as to satisfy the demand of extra-high voltage(EHV) distribution device’s high parameter, high reliability, easy running. The circuit breaker
be superior to domestic like products. It is the first choice of 550KV power system;
The main characteristics:
Good breaking capacity to fault.
The circuit breaker uses the principle of self arc-extinguish. The spout is designed by simulated analysis. It has the excellent performance of arc-extinguish. The short-circuit breaking current is 63KA, and the arcing time is short. The operation noise is small.
Long electrical life
The arc-extinguish chamber owns lots of patent technology. The spout and arc contact uses new arc resistant material. The main contact uses new structure,and the insulation tank between fractures uses new process. Free-maintenance in the condition of continues breaking 63KA short circuit current 20 times.
The high insulation level
The arc-extinguish chamber is optimally designed by Ansys.It owns lots of patent. The furnace of electrode uses electrostatic coating technology. The insulation level has reached the highest standard of GB1984 and IEC62271.
Great peak current
The contact of main conductive loop uses new Copper alloy materials and spiral spring contact and so on with small volume, good conductive performance, high dynamic reliability. It can run with 5000A current.
High mechanical reliability
The circuit breaker is equipped with ABB HMB-8 spring operation structure with high reliable operation. Free-maintenance in the condition of continues 10000 times operation.
The main structure:
Arc-extinguish chamber
It is designed according to auto arc-extinguish principle.
- Q:Transmission system and distribution system
- Distribution system is the power supply to the distribution load for the purpose of the general voltage level of not more than 10KV
- Q:What are the general requirements for working on distribution equipment?
- When the high voltage line is not cut off, the person in charge of the work shall explain to the whole staff that there is electricity on the line and strengthen the monitoring
- Q:Power distribution equipment should be prepared before the blackout?
- Before the power failure, the person in charge or the electrical appliance technician should fill in the work order.
- Q:What is the difference between power supply and distribution
- The two is the integration of power generation and power supply.
- Q:An introduction to the interpretation of flexible AC transmission systems
- synchronous compensator (STATCOM), reactive power distribution is mainly used to improve the system, to adjust voltage and improve the voltage stability of the system;
- Q:DC transmission equipment
- Power supply operation of power plant and substation in nowadays are used in DC power supply, it provides power for the control of the load and power load and DC emergency lighting load, is the foundation of modern electric power system control and protection
- Q:Transmission lines are not electrical equipment?
- Transmission lines in the power transmission project belongs to the carrier, belonging to the power cable category, should not be called equipment
- Q:Main equipment of high voltage direct current transmission
- At present, most of the converter adopts thyristor thyristor rectifier, which is composed of three phase bridge rectifier.
- Q:Difference between distribution voltage and supply voltage
- Supply voltage refers to the supply point of the line voltage or phase voltage.
- Q:AC distribution equipment including distribution box
- Connect the power supply, transformer, converter and other equipment for load distribution box, and monitoring
