Product Description:

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:Rural high voltage transmission line equipment ownership
You do not want to what the transformer behind the high-voltage line,
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:High and low voltage distribution equipment
Low voltage distribution equipment: low voltage distribution panel, switch cabinet, switch board, lighting box, power box and motor control center.
Q:Transmission and transformation equipment
High voltage has a very high risk, and the target electrical appliances do not need such a high voltage, which needs to reduce the voltage through the transformer
Q:What is the role of transmission system and distribution system in power grid
The distribution of power resources and power load centers in most countries in the world is inconsistent.
Q:Power distribution equipment should be prepared before the blackout?
electrician received power outage notice, pull down the knife switch, accept fuse.
Q:AC distribution equipment including distribution box
so there will be in the power distribution cabinet a reference line and a zero line selection of single-phase 6A can switch.
Q:What are the distribution network equipment
The transmission function of the power plants issued by the electricity to power consumption areas, or between adjacent grid power to send each other
Q:What are the general requirements for working on distribution equipment?
Common type cable connector used in power distribution equipment
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;
