Abstract
The utility model relates to an indoor alternating current high voltage sulfur hexafluoride load switch, including casing, static contact, moving contact, arc extinguishing bars, mainly be that the casing adopts epoxy three -phase boxed structure altogether, the casing inner chamber fills the sulfur hexafluoride gas of dress 0.04MPa atmospheric pressure, at the shells inner wall of moving contact left side below installation ground connection stationary contact sword, the right side sets up epoxy resin casting's bearing frame, and install on the bearing frame through the bearing at the major axis middle part, and one end and the one end of turning arm connecting rod of major axis are connected, the other end connection spring -operated mechanism of major axis, the other end of turning arm connecting rod and move contact connection. Its is small, installation space is little, is applicable to the 40.5kV high voltage electricity system.
Description
Technical field
This utility model belongs to power switchgear, specifically about a kind of sulfur hexafluoride loading switch. This utility model is applicable to 40.5kV high-voltage electric power system on-load switch.
Background technology
At present; at FLN36-12D/T630-20 and the FLN36-24D/T360-20 type indoor alternating current high voltage sulfur hexafluoride load switch that power system commonly uses; control suitable in 12kV and 24kV three-phase alternating current Force system and protection equipment, be particularly suited for ring main unit, cable distribution box and distribution switching station. But, the indoor alternating current high voltage sulfur hexafluoride load switch of existing mechanism, being not applied for using in rated voltage 40.5kV high-voltage electric power system, can only adopt vacuum load switch or vacuum circuit breaker in rated voltage 40.5kV high-voltage electric power system, small product size is big, installing space is big.
Summary of the invention
The purpose of this utility model is a kind of FLN36-40.5D/T630-20 type of exploitation, and volume is little, installing space is little, it is adaptable to the indoor alternating current high voltage sulfur hexafluoride load switch of 40.5kV high-voltage electric power system.
The technical solution of the utility model includes housing, static contact, moving contact, arc-chute; Mainly housing adopts epoxy resin Threephase common-box structure, and housing cavity fills the sulfur hexafluoride gas of 0.04MPa air pressure; Inner walls in moving contact lower left installs ground connection quiescent contacting knife, right side arranges the bearing block of poured with epoxy resin, it is arranged on bearing block by bearing in the middle part of major axis, one end of major axis is connected with one end of connecting lever connecting rod, the other end of major axis connects spring operating mechanism, and the other end of connecting lever connecting rod is connected with moving contact.
The utility model has the advantages that housing adopts epoxy resin Threephase common-box structure, its volume is little, installing space is little, is particularly well-suited to rated voltage 40.5kV high-voltage electric power system.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
1 static contact, 2 arc-chutes, 3 upper covers, 4 moving contacts, 5 lower covers, 6 major axis, 7 connecting lever connecting rods, 8 ground connection quiescent contacting knifes.
Detailed description of the invention
Indoor alternating current high voltage sulfur hexafluoride load switch as shown in Figure 1, including housing, static contact 1, moving contact 4, arc-chute 2, housing is sealed installation by upper cover 3 and lower cover 5 and constitutes; Housing adopts epoxy resin Threephase common-box structure, and housing cavity fills the sulfur hexafluoride gas of 0.04MPa air pressure, as arc extinguishing and dielectric; Inner walls in moving contact 4 lower left installs ground connection quiescent contacting knife 8, right side arranges the bearing block of poured with epoxy resin, it is arranged on bearing block by bearing in the middle part of major axis 6, one end of major axis 6 is connected with one end of connecting lever connecting rod 7, the other end of major axis 6 connects spring operating mechanism, and the other end of connecting lever connecting rod 7 is connected with moving contact 4.Major axis 6 realizes combined floodgate and the separating brake of moving contact 4 and static contact 1 under spring operating mechanism effect, and the combined floodgate ground connection of moving contact 4 and ground connection quiescent contacting knife 8 operates.
