6The safe operation of electrical equipment, therefore the necessary regulation that arrives related standards makes SF
6The good operating condition of the long-term maintenance of electric primary equipment.
SF
6Density monitor verification work refers to verification SF
6Whether density monitor compares with the mock standard force value in 0.6Mpa rated pressure indicated value, 0.52Mpa alarm pressure indicated value, 0.5Mpa locking pressure indicated value, correct to observe indicated value, judges SF
6The density monitor indication accurately reaches the quality of contact action.
State Grid Corporation of China 2012 352 literary compositions " 18 great anti-accident measures of electrical network of State Grid Corporation of China " clearly stipulates: SF
6Connected mode between density monitor and the switchgear body should satisfy the requirement of not dismantling the verification density monitor.
Simultaneously because verification SF
6The density monitor workload is bigger, and developing a kind of need not the dismounting can charged verification SF
6The isolated plant of density monitor to shortening working hours, is increased work efficiency, and in time finds to exist the SF of abnormal failure
6Density monitor is significant.
The utility model content
According to above deficiency of the prior art, the technical problems to be solved in the utility model is: provide a kind of and can dismantle SF
6Density monitor can be charged to SF
6The compare SF of verification of density monitor
6The charged calibration equipment of density monitor.
SF provided by the utility model
6The charged calibration equipment of density monitor comprises gas admittance valve, variable valve, standard scale and air outlet valve, and gas admittance valve, variable valve, standard scale and air outlet valve are linked in sequence by loading line.
Be arranged on after described gas admittance valve, variable valve, standard scale and air outlet valve are connected successively in the assembling case, the display surface of the import of gas admittance valve, the outlet of air outlet valve, standard scale and the adjusting mouth of variable valve all are arranged on the same plane of assembling case.Be easy to carry, more convenient, quick when interface all uses at grade.
The import of described gas admittance valve and the exit of air outlet valve all are equipped with quick self-sealing joint.It is convenient to peg graft, good airproof performance, and assurance gas can not revealed.

Among the figure: 1, gas admittance valve; 2, loading line; 3, variable valve; 4, standard scale; 5, air outlet valve.
Embodiment
Below in conjunction with accompanying drawing embodiment of the present utility model is described further:
SF as shown in Figure 1
6The charged calibration equipment of density monitor comprises gas admittance valve 1, variable valve 3, standard scale 4 and air outlet valve 5, and gas admittance valve 1, variable valve 3, standard scale 4 and air outlet valve 5 are linked in sequence by loading line 2.Gas admittance valve 1, variable valve 3, standard scale 4 and be arranged on after air outlet valve 5 is connected successively in the assembling case, the adjusting mouth of the outlet of the import of gas admittance valve 1, air outlet valve 5, the display surface of standard scale 4 and variable valve 3 all is arranged on the same plane of assembling case.The exit of the import of gas admittance valve 1 and air outlet valve 5 all is equipped with quick self-sealing joint.Standard scale 4 is 0.25 grade of standard of accruacy table.
Checking process is: close the by-pass valve control of power transformation primary equipment body, cut off SF
6Density monitor links to each other with apparatus body; Should charged calibration equipment and SF
6Density monitor links to each other, with the SF that carries
6Gas cylinder is inflated to rated pressure in advance to it, with 4 couples of SF of standard scale
6Density monitor carries out verification, checks that rated pressure indicates whether accurately; Break away from SF
6Gas cylinder is exitted from gas admittance valve 1, reduces SF gradually
6Gaseous tension when treating that standard scale 4 pressure are indicated alarm pressure, locking pressure respectively, is observed SF
6Whether density monitor is accurate at these two scale readings, whether exceeds the numerical value deviation, and measures SF with multimeter
6Density monitor is reported to the police, the reliability of locking contact action; Venting is to zero gauge pressure, verification end-of-job gradually.
