Product Detail

Description：

UniGear 500R is very space efficient solution, designed to reduce the width of the medium-voltage airinsulated switchgear. Panel design is only 500 mm wide for feeder current up to 2000 A.Its compact design makes UniGear 500R ideal for container installation for primary distribution.  

One of the main characteristics of the UniGear 500R switchgear is the isolation of the circuit-breaker from the main busbars by means of the three position disconnector.

FAQ
Q： What’s the difference in the circuit breaker for air-insulated vs gas-insulated?
A： Air-insulated switchgear circuit breaker is typically removable or withdrawable. The circuit breaker is based on vacuum circuit technology. In the gas-insulated, it is fixed mounted. The function of withdraw is provided by a separate disconnecting switch. Typically, a three-position switch with connected, disconnected, and ready-to-earth position.
Q： What are the key features of ABB’s medium voltage switchgear products?
A： ABB‘s primary medium voltage switchgear products are designed to connect and protect the evolving grid. They feature robust construction, advanced safety mechanisms, high reliability, and ease of maintenance. They are designed to handle high electrical loads and provide efficient power distribution with minimal losses.

Failure Analysis and Design Optimization of Conventional Grounding Transformers
I. Core Cause of Damage: Electrodynamic Impact (Complying with GB/T 1094.5 / IEC 60076-5)The direct cause of high-voltage winding end collapse is the instantaneous electrodynamic impact induced by short-circuit current. When a single-phase grounding fault occurs in the system (such as lightning overvoltage, insulation breakdown, etc.), the grounding transformer, as the fault current path, withstands high-amplitude and steep-rise-rate short-circuit currents. According to Ampère's force law
