Solid-insulated switchgear MSIS89-40.5

Parameters

 

 

The MSIS89-40.5 series represents a cutting-edge solution in solid insulated switchgear technology, optimized for 40.5kV applications. This series is designed to enhance operational efficiency, safety, and reliability in power distribution networks. Below are the key functionalities that define the MSIS89-40.5 series:

Protective Functions:

Fault Identification: Automatically detects fault currents and implements instant current cut-off, time-limited current interruption, and other protective measures.

Comprehensive Protection: Offers an array of protections including overvoltage, undervoltage, single-phase ground protection for minor current ground systems, and safeguards against open circuits and cooling load start-ups.

Measurement Functions:

Accurately measures a wide range of electrical parameters including three-phase current and voltage, active and reactive power and energy, peak/valley electricity consumption, power factor, and frequency.

Control Functions:

Enables both local and remote control operations, facilitating rapid restoration of power to fault-free circuits, fault location and isolation, automatic load shedding in low-frequency scenarios, capacitor and backup power automatic disconnection.

Communication Functions:

Utilizes both wireless public networks and specialized communication networks to report faults, operations, and control information to designated personnel. Supports various communication protocols and allows for parameter modifications via handheld PDAs, including self-inspection commands and feedback.

Data Recording Function:

Automatically records, stores, and manages operational and fault data, ensuring a comprehensive historical record for analysis and decision-making.

Synchronous Switching Function:

Automatically identifies zero crossing points tailored to load characteristics, achieving synchronous switch on/off. This function effectively minimizes operation-induced overvoltage and inrush currents, making it particularly beneficial for capacitor and transformer operations.

Intelligence Function:

Performs online comprehensive analysis of network parameters and breaker performance measurement, supports online programming, and integrates with power distribution automation systems for remote control and management of switchgear operations.

Load Management Function:

In collaboration with AVR series intelligent compact solid insulation switchgear, it enables effective load management. This feature addresses electricity billing challenges for diverse customer segments including scattered residential, temporary, and non-compliant customers.

The MSIS89-40.5 series solid insulated switchgear is engineered to deliver a comprehensive suite of functionalities designed for modern power distribution needs, offering a blend of protection, efficiency, and smart operation capabilities.
