1 Overview
1.1 General Provisions
FCR21-40.5RD ( Embedded pole ) indoor high voltage ac vacuum load break switch + fuse combination, suitable for AC 50Hz, rated 40.5kV power system, is the company based on GB3804 and GB16926 design, suitable for ac 50Hz, rated voltage 40.5kV network, for wind power and solar power 35kV system design, can be used as independent electrical units in 40.5kV power system or box type substation. This product has a reasonable structure, and a simple and reliable action.
This product has the advantages of large breaking ability, safety and reliability, long electrical life, frequent operation, less maintenance and so on. At the same time, it has obvious isolation break and a grounding knife with closing ability, with electric spring operating mechanism, and remote control ability.
EC 62271-105:2021 High-voltage switchgear and controlgear - Part 105: Alternating current switch-fuse combinations for rated voltages above 1 kV up to and including 52 k V
GB 16926 High-voltage AC load break switch fuse combination electrical appliances
GB3804 High-voltage AC load break switch
GB / T 1985 high voltage AC disconnecting switch and ground switch
1.4.1 Normal operating conditions
The normal service conditions of load break switch meet the requirements of GB / T 1984, DL / T 403:
Altitude: not exceeding 2000m
Surrounding air temperature: upper limit + 40℃, lower limit-25℃
Relative humidity: daily average is not more than 95%, monthly average is not more than 90%
No corrosion or combustible gas around other obvious pollution
No regular and violent vibration
1.4.2 Special conditions of use
For special operating conditions different from normal operating conditions, please negotiate with the manufacturer and reach a consensus before use. The company will give special processing to the circuit breakers to meet your operating environment requirements.
1.5 Product features
Modular design, with cabinet "five prevention" simple, reliable and consistent:
The dominant electric circuit is in the form of fixed sealing pole column. It avoids the pollution of the outdoor surface of vacuum arc extinguishing, increases the creepage distance along the surface, improves the insulation level of the load break switch , the modular design of the fixed sealing pole column, simple structure, less removable parts, has stable mechanical properties and insulation performance;
High voltage vacuum load break switch , load break switch and grounding switch with obvious isolation switch:
All state display and operation are integrated in the operation panel of the equipment, through the intuitive concise man-machine dialogue interface, all status and operation steps at a glance, can intuitively observe the isolation switch, ground switch, load break switch switch exact status, effectively guarantee the safety of operators and equipment, easy to understand, to avoid misoperation;
