Two other port of the threeway live check instrument connects SF respectively6Gas density relay and charging valve.
Preferably, the through hole on the bottom plate is penetrated along unilateral horizontal direction and set.
Preferably, bottom plate and connecting tube, connecting tube and threeway live check instrument, threeway live check instrument and SF6Gas is close
Degree relay and charging valve are connected by connecting standard component.
Further, it is bolt to connect standard component；Connecting tube and through hole are bolted sealed connection in the axial direction.
Preferably, it is provided with sealing ring between the connecting tube and bottom plate and threeway live check instrument.
Preferably, the sealing ring uses O-ring.
Preferably, the connecting tube free end is provided with the anglec of rotation, the SF connected on threeway live check instrument6Gas is close
Degree relay and bottom plate stagger setting at an acute angle.
Preferably, the connecting tube is made by justifying aluminium bar through integrally machining to be integrally formed.
Compared with prior art, the utility model has technique effect beneficial below：
The utility model is by integrally formed connecting tube one end connecting bottom board side of setting, and the other end is with being connected SF6
Gas density relay is connected with the threeway live check instrument of charging valve.The attachment structure of more original connecting bottom board bottom, more
Add and be easily installed, dismantle, overhaul and change.By being tightly connected between connecting tube and bottom plate and threeway live check instrument, prevent
It is being filled with SF6Gas leakage occurs during gas and after inflation；
Further, by connecting standard component connecting bottom board and connecting tube, connecting tube and threeway live check instrument, three passbands
Electric tester and SF6Gas density relay and charging valve, stable connection；
Further, can be by SF by the way that the free end of connecting tube to be provided with to certain anglec of rotation6Gas density after
Electrical equipment and bottom plate stagger setting, it is convenient to read SF6The instrumented data of gas density relay, design more hommization；
Further, the connecting tube added by circle aluminium bar through integrated machine more originally reduced welding link, improved production
The air-tightness of product, while material cost and processing cost are reduced, improve the competitiveness of product in market.
