Product Detail

Description:

VD4 evo circuit breakers are used in power distribution systems for controlling and protecting cables, transformer and distribution substations, motors, transformers and capacitor banks. VD4 evo includes a range of sensors for a seamless transition from traditional to digitally connected medium voltage circuit breakers. The integrated sensors enable advanced monitoring and diagnostic features for real-time monitoring of thermal, mechanical, and electrical parameters, allowing remote asset management and thus reducing maintenance cost and contributing to reduced downtime.
VD4 evo is also available in standard configurations without sensors. The flexibility of the design enables future digital upgrades, including sensors, if required.

Features:

  • Full monitoring and diagnostics (M&D) flexibility.
  • Mechanical chain and accessories anomalies detection.
  • Loose connections detection and circuit breaker contacts monitoring.
  • Advanced thermal checks & electrical life.
  • The most compact medium voltage circuit breaker selection for your application.
  • Third-party verified Environmental Product Declaration (EPD) for transparency of the environmental impact of the circuit breaker.
  • QR code for fast retrieval of online documentation.
  • Intuitive dashboard based on the Web browser-based HMI.

 Technical Characteristics:

Scope:

  • Withdrawable and fixed medium voltage circuit breakers for primary distribution.
  • The digital evolution of the IEC indoor vacuum circuit breaker VD4.
  • VD4 evo p150 17.5 kV, up to 1250 A, 40 kA withdrawable (for UniGear ZS1 650 mm) and fixed.
  • More ratings to be released soon.

Benefits:

  • New intelligence reduces the risk of power outages by 30 percent and increases operation and maintenance efficiencies by as much as 60 percent.
  • Enables reduced operating expenses (OpEx) by reducing outages and maintenance cost.
  • The most compact 17 kV 40 kA breaker, enabling 15 percent of space saving.
  • VD4 evo can be directly integrated with ABB’s ZEE600 SCADA solution enabling a direct cloud connection, or alternatively integrated with a third-party SCADA and gateway.

FAQ
Q: What inspections should be performed after a short-circuit fault in a vacuum circuit breaker?
A: Check contact erosion: Minor erosion is acceptable (cumulative wear ≤3mm), but replace the vacuum interrupter if damage is severe. Test switching time and synchronization: Ensure values meet specifications to prevent operational issues caused by mechanism changes. Clean arc byproducts: Remove debris from the interrupter surface and inspect insulation components for impact damage or cracks.
Q: How to determine if a vacuum interrupter has failed?
A: Visual inspection: Check for cracks in the glass/ceramic housing or oxidation/discoloration of the internal shield. Vacuum degree detection: Use a high-frequency spark leak detector or professional vacuum degree tester. Replace the interrupter immediately if the vacuum degree decreases. Withstand voltage test: Perform a power frequency withstand voltage test at the rated voltage (e.g., 42kV/1min for 12kV products). Failure indicates the interrupter has failed.

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

1 Theoretical AnalysisIn distribution networks, grounding transformers serve two key roles: powering low - voltage loads and connecting arc - suppression coils at neutrals for grounding protection. Grounding faults, the most common distribution network fault, heavily impact transformers’ operating characteristics, causing sharp changes in electromagnetic parameters and status.To study transformers’ dynamic behaviors under single - phase grounding faults, build this model: Assume a tr

In a neutral-insulated three-phase power system, an earthing transformer provides an artificial neutral point, which can be solidly earthed or earthed via reactors/arc suppression coils. The ZNyn11 connection is typical, where zero-sequence magnetomotive forces in the inner/outer half-windings of the same core column cancel out, balancing fault currents in series windings and minimizing zero-sequence leakage flux/impedance.Zero-sequence impedance is critical: it determines fault current magnitud

The neutral grounding mode refers to the connection between the power system neutral point and ground. In China's 35 kV and below systems, common methods include ungrounded neutral, arc-suppression coil grounding, and small-resistance grounding. The ungrounded mode is widely used as it allows short-term operation during single-phase grounding faults, while small-resistance grounding has become mainstream for its fast fault removal and overvoltage limitation. Many substations install grounding tr

Discussion on the Design of Low Zero-Sequence Impedance Grounding Transformers
With the expansion of power system scale and the cableization process of urban power grids, the capacitive current in 6kV/10kV/35kV power grids has significantly increased (generally exceeding 10A). As power grids at this voltage level mostly adopt neutral ungrounded operation mode, and the distribution voltage side of main transformers is usually in delta connection, lacking a natural grounding point, the arc during ground faults cannot be reliably extinguished, necessitating the introduction o
