Product Detail

Description

LW35 serial circuit breakers, including LW35-72.5, LW35-126, LW35-145 and LW35-252 products, are designed with self-energizing principle that arc generated in the interrupter is distinguished at a specified time with a part of energy produced by the arc itself. They are used for making and breaking normal current, fault current and switching lines to realize the operation (three-pole opening & closing operation and fast automatic-reclosing operation),  control and protection of power system.


Main Features


  • Less consumption of SF6 gas, benefitial for environmental protection. When other kinds of circuit breaker at 0.6 MPa must be filled with SF6 of 27 kg/set, this kind of circuit breaker only need 19.3 kg/set.

  • Dynamic sealing system adopts advanced Glyd-ring and Step seal to reduce starting friction and prevent leakage.

  • Adopt imported control valve of stable performance and anti-slow-opening function in case of pressure loss.

  • Two sets of independent opening control circuit are adopted in hydraulic mechanism with two sets of relay protection to enhance service reliability.

What are the purity requirements for SF6 gas in the interrupter of a tank circuit breaker?

  • SF₆ Gas Purity: The purity of SF₆ gas is generally required to be 99.8% or higher. High-purity SF₆ gas ensures its excellent insulating and arc-quenching performance. The presence of impurities can reduce the insulation strength and arc-quenching capability of SF₆ gas. For example, contaminants such as moisture and air can affect the ionization process and the cooling effect of the arc.

  • Toxic and Harmful Substances: When SF₆ gas contains a significant amount of impurities, it may produce more toxic and harmful substances under the influence of the arc, posing greater risks to both equipment and human health.

What should be noted when selecting and installing GIS voltage transformers?
What should be noted when selecting and installing GIS voltage transformers?
In power systems, voltage transformers in GIS (Gas Insulated Switchgear) play a crucial role in voltage measurement and relay protection. Selecting the right model and installing it correctly is vital for the stable operation of the equipment. The following points should be noted regarding selection and installation.I. Key Points for Selection(1) Matching Rated ParametersVoltage Level: It must be consistent with the voltage level of the GIS system. For example, 110kV and 220kV GIS systems requir

1. Accident Overview1.1 Structure and Connection of 35kV GIS Switchgear Voltage TransformerThe ZX2 gas-insulated double-bus switchgear, manufactured in March 2011 and officially put into operation in July 2012, is configured with two groups of bus voltage transformers (PTs) for each bus section. The two PT groups of the same bus section are designed in one switchgear cabinet with a width of 600 mm. The three-phase PTs are arranged in a triangular formation at the bottom of the cabinet.The PTs ar

What Are the Steps for Error Testing GIS Voltage Transformers?
Hey everyone, I'm Oliver, and I've been working with current transformers (CTs) and voltage transformers (VTs) for 8 years.From assisting my mentor on site to leading high-voltage testing teams and conducting error calibrations independently, I’ve dealt with all kinds of instrument transformers — especially those used in GIS systems. The error test for voltage transformers is something I perform regularly.A few days ago, a friend asked me:“Oliver, how exactly do you perform an

Operation Method for PT Resonance in 500kV GIS Switching Station
Operation Method for PT Resonance in 500kV GIS Switching Station
1. Causes of ResonanceA 500kV GIS switching station is designed following the principle of “primary equipment intelligence and secondary equipment networking”. The PT high - voltage side has no disconnector and is directly connected to the bus GIS. Through the analysis of fault recording diagrams, when the 5021 circuit breaker opens, the fracture capacitance and PT form a series circuit. Moreover, the bus voltage, after being paralleled by the PT inductance, shows inductive character

Hi everyone, I'm James, and I've been working with current transformers (CTs) for 10 years. Today, I’ll talk about what you need to watch out for when selecting and installing GIS current transformers.Part 1: Key Considerations During Selection1. Accuracy ClassProtection-grade CTs: Used for relay protection — focus on overload capacity and transient response.Metering-grade CTs: Used for billing purposes — require high accuracy, usually 0.2S or 0.5S class.2.
