Cable type indicator manual
The cable circuit trouble indicator is installed in case becoming, cable branched case, ring network cupboard, point out the device of the cable with branched trouble. Device used for pointing out the electric current of trouble circulates. Once the short circuit trouble takes place in the circuit, patrolling line personnel can call the police to reveal through the flash of light on the indicator, confirm the sector of trouble, branch and trouble point rapidly. Makeover, patrol line blindly in the past, shut floodgate, try, transmit power, find out backward method of trouble by stage, the great one raised working efficiency, effective shortening lost electrical power for time, and improved power supply reliability and economic benefits.
Indicator of trouble that first, cable circuit short out
Trouble criterion ( 1) of the short circuit 1t≥ 300A 1t, for the starting value of electric current of sudden change amount
( 2) 1≥ 0.510 Rate of change of a electric current 10, for the electric current of circuit before shorting out
( 2) 1 =0 1 is the electric current after the circuit trouble
( 4) 0.02S≤ T≤ 2S T is the sudden change time of electric current
The indicator of trouble that the cable circuit shorts out, each set of standard configurations is three short circuit indicators, short out indicator measure trouble of shorting out, can measure trouble of shorting out.
Indicator of trouble that second, cable circuit short out
Technical parameter:
The movement response time of short circuit: 0.02s≤ T≤ 4S
Working environment range: -40 ¡æ& mdash; +85 ¡æ
Working power: Dispose 2000 milliamperes per hour lithium one battery, service life is 5 years, voltage 3V
The time of resetting automatically: Load and unload artificially and simply in 17 hours: Need, install tool, can load and unload the indicator while being charged while being specialized.
Line range: Cable diameter ( Take the crust) ≤ ¢ 40mm
The cable circuit trouble indicator is installed in case becoming, cable branched case, ring network cupboard, point out the device of the cable with branched trouble.

Manage the trouble indicator of the voltage transformer, the mutual inductor mainly more than excellent special Utilities Electric Co.,Ltd., the trouble indicator of the panel, impracticable trouble indicator, the cable trouble indicator cable shorts out the trouble indicator cable branches off the case trouble indicator photoelectricity and reveals DS-2DG;
