1. Function requirements for three-way valve group of SF6 gas density relay
(1) When the high-voltage switch is disassembled without power failure, there is no need to disassemble the screw, and the b can be checked and replaced on line.
(2) After the on-line calibration equipment is installed, it is very convenient to carry out micro-water measurement, air supplement, decomposition product test and purity test on the high-voltage switch of SF6 relay.
(3) The stop valve body of SF6 relay has obvious position indication of valve body switch, and it is equipped with special tools for the operation of stop valve.
(4) The non-assembled three-way valve of SF6 relay can be calibrated or replaced without disassembling the SF6 relay.
(5) The non-assembled three-way valve of SF6 relay can be operated independently which is convenient, labor-saving and time-saving.
2. Functional characteristics of control three-way valve group of SF6 gas density relay
(1) It can be matched with various specifications of switch interfaces.
(2) it is very convenient to carry out micro-water measurement, air supplement, decomposition product test and purity test on the high-voltage switch of SF6 relay.
(3) The manual valve operation is simple and flexible, and the valve body structure of the spherical valve and the needle valve can be customized freely.
(4) The valve body is made of imported stainless steel gold-plated one-piece needle valve.
3. The technical indicators of control three-way valve group of SF6 gas density relay
(1) The valve body is fully imported stainless steel gold-plated one-piece needle valve.
(2) Pressure rating: PN64.
(3) Sealing performance: air leakage rate ≤1×10-15Pa.m3/s.
(4) Impact resistance: 600m/s2; impact time: 11ms.
(5) Corrosion environment test: IEC60068-2-11 standard test.
(6) Ambient temperature: -50 to +100℃.
(7) Service life: 100,000 times (on-line detection of switching times of valve).
