DXN8D INDOOR HV CHARGED DISPLAY DEVICES VPIS SERIES HX2-2 TYPE PHASE COMPARATOR PC

Description:

HX2 type phase comparator (PC) is matched with DXN8D series indoor HV charged display devices (the indicator panel sets the phase testing end). It is applied to indoor 3.6-40.5kV, 50Hz HV charged display dual power, multipower supply substation, distribution substation (especially for inlet cable). After inspection and before transmission, operator could compare the phases by LV end without opening the switchgear door.

  • Product Description

Summarize

HX2 type phase comparator (PC) is matched with DXN8D series indoor HV charged display devices (the indicator panel sets the phase testing end). It is applied to indoor 3.6-40.5kV, 50Hz HV charged display dual power, multipower supply substation, distribution substation (especially for inlet cable). After inspection and before transmission, operator could compare the phases by LV end without opening the switchgear door.

 

Using method

 

Before phase  comparison, operator should make sure all wirings are correct within HV switchgear, namely the sequenves of cables between voltage sensor and voltage indicator are right. When two HV powers are supplying normally, operator should do the following steps after making sure all voltage indicator are normally working: Insert one plug of the comparator end into L1 phase testing end on the voltage indicator of working power switchgear, then insert the other plug of the comparator end into L1,L2,L3 phase testing end separately on the voltage indicator panels of pending power supply switchgear, to observe the indicator light conditions of comparator.

Technical parameter

The internal adopts lower power consumption Neon bulb light emitting element, when input voltage is over 60V, the indicating lamp of comparator lights up

When phase are the same, the indicating lamp will not light up

When pahses are different, the indicating lamp will light up

Two ends of comparator adopts 4mm standard banana plug, the length of testing cable: 2m
