There is no the type technical products on the market, helps nodal test usually to need to carry out by manual type 10kV breaker；Wherein
The auxiliary node detection work of 10kV breaker is that 10kV overhaul of line breaker must do link, can pass through the inspection to auxiliary node
It surveys to judge whether the reliability of switch motion is up to standard；This work at present is that multimeter is held by staff in secondary plug
On to each auxiliary node carry out one by onechecking.This detection mode has the following problems: 1, injury device: the two of breaker
Secondary plug pedestal material is generally flame-retarded plastic, and as the age increases, intensity is gradually weakened；Meanwhile the pointer of secondary plug
Generally there is certain contact to spend in advance and compares loosening；Lead to the test pencil of the hand-held multimeter of staff work on the pointer of secondary plug
When making, it is easy to appear that dynamics is too small can not accurately to measure numerical value, dynamics is excessive and the phenomenon that injuring pointer.2, working efficiency is low:
The secondary plug of each 10kV breaker has general 30 pointers (depending on breaker model), and every two pointer can measure one
A experimental data, and each data will correspond to two kinds of working conditions of ON/OFF, therefore one switchs this service work and needs weight
Operating again could complete for 20 times or more, also not include the repetition situation of poor contact.
In conclusion problem of the existing technology is:
1. the intricate operation of detection breaker auxiliary node, low efficiency manually；
2. the phenomenon of the presence inaccuracy of detection breaker auxiliary node manually；
3. detection breaker auxiliary node can damage the pointer of secondary plug manually for a long time；
It is existing that multimeter is held on secondary plug to each auxiliary node progress one by onechecking by staff
Detection mode has that injury device, working efficiency are low.
