UT-Z300S Secondary intelligent monitoring system

Secondary equipment is responsible for monitoring, controlling, regulating, and protecting primary equipment, forming a critical part of protection and control circuits. The correctness of secondary equipment status directly affects the stability and reliable operation of the primary system. As the one-key sequence control mode is promoted in the power grid, secondary equipment such as locking plates, circuit breakers, and switching handles, which cannot be operated remotely, still require on-site manual operation by O&M personnel. This significantly limits the rapid development of the one-key sequence control mode. The intelligent secondary monitoring system enables comprehensive monitoring of secondary equipment status, remote control, status inspection, secondary anti-error, and online analysis. It effectively resolves issues such as low efficiency in manual inspections, high risks of human error, and low levels of intelligence in secondary equipment, providing strong technical support for the construction of new intelligent power grids.

Product Advantages

Comprehensive status monitoring

Comprehensive status monitoring

It enables online monitoring of the operational status, settings, circuit status (including voltage), and communication links for secondary equipment, providing a panoramic view of secondary equipment status at substations.

Secondary equipment remote control

Secondary equipment remote control

By using microelectromechanical control technology, the system enables remote intelligent control of secondary equipment like pressing boards, circuit breakers, and switching handles, significantly improving the operational efficiency of secondary equipment.

Secondary anti-misoperation

Secondary anti-misoperation

Building on primary anti-error verification, it expands the anti-error functionality to secondary equipment, achieving mutual verification between primary and secondary equipment as well as operation guidance. This prevents misoperations in secondary equipment, enhancing the safety of disconnector operations.

Intelligent analysis and diagnosis

Intelligent analysis and diagnosis

The system performs automatic inspections of secondary equipment, setting value checks, circuit status analysis, protection action analysis, status inconsistency analysis, intelligent defect diagnosis, and automatic ticketing for secondary safety measures, which improves O&M efficiency and safety levels.

Disconnector Double-Confirmation Solution for Substations

Disconnector Double-Confirmation Solution for Substations

The magnetic induction double-confirmation device mainly consists of a magnetic induction sensor and a receiving device. The magnetic induction sensor uses a non-contact induction principle to detect the status of the disconnector and transmit the status information to the receiving device. The receiving device is installed in the control cabinet, terminal box, or independent cabinet, achieving logical calculation and status output of the disconnector status signal. The magnetic induction double-confirmation device features safe and reliable non-contact detection, easy installation, and suitability for various equipment types and operating environments. It accurately identifies the open/close status of disconnectors, providing a more secure and reliable technical guarantee for one-click sequence control.
