Detailed description of the invention
As it is shown in figure 1, this utility model is when carrying out the work of spark gap charged for replacement leakage current table, this special complete work
Tool can carry out modularization assembling, multiple specific purpose tool compound mode.
This special complete instrument entirety is a workbox, and the upper cover 10 in workbox and box body 2 are exhausted by epoxy resin etc.
The compacting of edge material forms, and the corner correspondence position at upper cover 10 and box body 2 all has screw 9, and the screw 9 of upper cover 10 and box body 2 is used
In fixed insulation pillar 7, insulation column 7 should be, intensity reliable porcelain insulator good with full skirt, insulation or compound inslation
Son, there is screw rod at insulator 1 two ends, are securable to the screw 9 of corner.
Staff can stand on above the upper cover 10 in workbox when charged for replacement leakage current table 13；In box body 2
There are placement down conductor continuity test instrument 3, circuit tester 4, adjustable wrench 5, fork spanner 6, insulation column 7 and with fixing spiral shell in portion
The short circuit copper strips 8 of bolt, short circuit copper strips 8 is two, and cross section is 60mm*10mm, a length of 0.8m.
The concrete steps of operational method:
Step one: operating personnel, before changing fault leakage current table 13, confirms this spark gap 1 current in resistance property live detection
Result is qualified, and lightning arrester body is without exception；If lightning arrester body existing defects, this work can not be carried out.
Step 2: as in figure 2 it is shown, under operating personnel uses down conductor continuity test instrument 3 to draw this arrester ground
Line 12 the most well judges with main earth mat connection, and spark gap 1 ground connection should be reliable.
Step 3: operating personnel uses upper cover 10, box body 2 and insulation column 7 to assemble easy insulating support, uses absolutely
Should confirm before edge support that support is the most steady, then start operation；The purpose using insulating support is to protect operating personnel, anti-
Only operating personnel is subjected to the floating potential injury that maloperation may cause.
As it is shown on figure 3,
Step 4: operating personnel uses two 8 leakage current table 13 short circuits of short circuit copper strips with fixing bolt, two
Being intended to reliable short circuit, now leakage current table 13 reading should return 0, uses circuit tester 4 to measure whether leakage current table 1 makes after short circuit
On leakage current table, lead-in wire 11 and down conductor 12 are reliably connected.Use two to be in order at dual fail-safe to consider, prevent one
Root occurs that loose or dislocation situation occurs.
Step 5: after reliable short circuit leakage current table 13, uses the Work tool such as adjustable wrench 5, fork spanner 6 to leakage electricity
Stream table is replaced, and the leakage current table 13 after replacing answers reading good.
Step 6: remove short circuit copper strips 8.
Step 7: site clearing, confirms without leaving over object.
