产品描述

Parameters

Summary
The KXGN - 12 type user demarcation switch cabinet equipment widely used in cables of rated voltage 12kV, rated frequency 50Hz tap, segmented, and multiple power point contact, applicable to the city underground cable ring and radiant power line and the control and the connection, and underground cables and overhead line hybrid net import line control and connection, realize the ring network power supply and radiation power. The product has the unique function of automatically removing branch line, grounding fault and interphase short circuit fault, which is called the function of dividing switch cabinet or watchdog function. It is a new high-tech product integrated with vacuum switch cabinet technology and microelectronic intelligent control technology.

Product model definition

typical application

1.Single switch multi-loop outdoor cable branch box

Into four out of the program Into four with a ring out (load switch) program

use
Generally used for outdoor cable tapping and cable-specific branch line monitoring. Can be protected branch of the single-phase control of the ground and short-circuit fault will not affect the trunk and adjacent lines；
Can be configured as an integrated electric, can also be made into a full manual configuration, the maximum cable tap capacity into one into four.

Monitoring of specific branch lines of cables.
Can protect the branch of the alleged single-phase ground fault and short-circuit fault will not affect the trunk and adjacent lines;
Multi-circuit bus expansion.
When the fixed cabinet type can not meet the requirements of the number of multi-circuit solutions in a single line, it can be used as an expansion cabinet type and realize the fault monitoring function.
Upgrading of the existing lines, do not have the watchdog function of existing branch line into the switchgear, branch line monitoring.
