The main features introduced:

1 , zero sequence protection function

When a ground fault occurs in the branch line user and the end user line, the

d e marcation breaker controller detects the zero-sequence current.After the delay is determined to be a permanent fault, the controller outputs the opening commandto automatically divide the demarcation vacuum breaker and automatically cutln addition to ground faults, other users in substations and feeders do not experience theoccurrence of faults.

2 , quick-break protection

Short-circuit currents are detected by the demarcation breaker controller when a short-circuitfault occurs in the branch line users and the end-user line.

The controller immediately outputs the opening command so that the demarcated vacuumcircuit breaker automatically opens,automatically removes the short circuit fault, substation andfeedOther users on the line are protected from power outages.

3, over-current protection

When an over-current fault occurs in the branch line user and the end-user line, the

demarcation breaker controller detects the over-current.After the time delay is determined, thecontroller outputs the opening command to automatically divide the demarcated vacuum circuitbreaker and automatically remove the overcurrent fault.Substations and other users on feedersavoid blackouts.

4, reclosing function

ln order to prevent the user from power failure for a long time due to a transient fault, after theprotection action of the controller, the circuit breaker

Line reclosing, reclosing times, time can be set, reclosing up to 3 times.5、Acceleration after reclosing

ln order to avoid permanent damage to the line caused serious damage, or other protection ofthe time limit, the controller does

Acceleration protection after reclosing.6 , quickly locate fault liability

After the user of the branch line user and the end user of the line demarcate the vacuum circuitbreaker protection action, only the responsible user is powered off, and the user

After unsolicited reporting of fault information, the power department can quickly determine thefault point and immediately go to the fault site to troubleshoot the fault; such as demarcationThe circuit breaker controller is equipped with a communication module,and the information isautomatically reported to the power management center, avoiding long-term fault checking.Inquiries and issues related to the responsibility of the power sector and users.

7 , monitor user information

The demarcation breaker controller can be equipped with wired or wireless communicationmodules to transmit monitoring data to the power management center.

Realize remote real-time data monitoring of user information, truly achieve "four remote' functionsand automatic reporting of faults to the Ministry of Supervision door.

8, a wide range of applications

The complete set of equipment is suitable for ungrounded neutral points, neutral arc-extinguishing ring grounded or neutral grounded by small resistance 10kv or 6kv distribution network system.

9 , flexible outlet

Outlet can use silicone rubber sleeve,can also be equipped with fully insulated outlet cable.10, switching power supply flexibility

Switching powersupply can choose large-capacity externalTV (primary with a fusion tube),can also be configured with integrated Tv.

1Overview

Main use and application scope

When a 10kV overhead distribution line T is connected to a user inside a fault, if the fault is onthe incoming line, or the fault occurs,

When the user enters the line switch, but the time limit of its protection action is not properlymatched with the substation outlet switch protection， it will cause changes.The power stationoutlet switch protects the gate. If the nature of the fault is permanent and the substation reclosingfails, a medium voltage user The accidents in the sector will cause the entire distribution line to bepowered off. This type of common accident in the distribution network will cause harm tosociety.Bad influence.The user demarcation switch is the ideal equipment to solve the abovecontroversy accidents, the responsibility of the equipment installed in the 10kv overheaddistribution line At the demarcation point, it is possible to automatically cut off single-phase groundfaults and automatically isolate phase-to-phase short-circuit faults.
