Description
Product overview
This product has three working positions: “closing”, “breaking” and “grounding”;
It conforms to the relevant requirements of GBT 11022-2011 “Common technical requirements for high-voltage switchgear and control equipment standards” and GB3804-2017 “3.6kV~40.5kV high-voltage AC load switch”.
Use of the environment
◎Altitude: ≤2000m; seismic intensity: 8 degrees;
◎ Normal working temperature: -30℃～60℃;
◎ Frequent violent vibration of the installation site, obviously affect the performance of the institution of water vapor, gas, chemical etching deposits, salt spray, dust and dirt and its fire, explosion risk of the installation site is not suitable for use;
◎ The surrounding relative humidity: relative humidity daily average ≤ 90%, monthly average ≤ 90%;
Spring operating mechanism (K type)
Spring operating mechanism (A Type)
The closing operation of the load switch
Plugging the operating handle into the hole of the closing operation shaft (lower right corner) clockwise rotation for 180℃, themechanism leads the contact to complete the closing operation of the load switch quickly. At the same time the spring with energystorage is ready for tripping.
The opening operation of the load switch
Just stiring the tripping by opening button. the opening spring energy is released. and mechanism leads the principal shaft to complete the opening operation quickly.
The grounding operation of the load switch
The grounding operation of (A Type) spring operation mechanism is same to the (K type).
Note:
1. The spring operation mechanism with outgoing line include the functions of the fuse tripping, manual tripping knob. Inaddition, it can include tripping coil and overcurrent tipping coil.
2. If users order elecric spring operation mechanism, please note the rate of voltage ( such as DC220, DC110, DC48, DC24)
3. If users need the shunt trip coil, please specify the rate of the voltage, or it is recognized the same voltage level as the electricoperating motor.
