H(l)6-24 630/20 sf6 fully insulated metal-enclosed compact switchgear
Standard specification
H(L)6-24 series SF6 fully insulated and fully enclosed compact ring network cabinet (hereinafter referred to as inflatable cabinet) is suitable for three-phase AC 50Hz, rated voltage 24kV power distribution system.
It can be used as a load current, an overload current, and a short circuit. It can also break capacitive loads such as no-load transformers, fixed-line overhead lines, cable lines and capacitor banks, and generate power in the power system.
Distribution, control and protection.h(l)6-24 adopts a fully sealed structure, all of which are sealed in a gas chamber welded by a stainless steel plate with a protection rating of ip67.
It can adapt to humid and salty fog, such as flood, heavy pollution and other harsh environmental conditions, and operate safe and reliable multi-loop ring network switchgear.Widely used in industrial parks, streets, airports,
Residential areas, prosperous commercial centers, etc., are ideal equipment for distribution network automation.Also used in: compact box-type substations, cable branch boxes, opening and closing, wind power stations, subways and tunnels.
H(l)6-12/24 Available modules are:
C — load switch module
De - cable connection module with grounding knife
Df—cable connection module without grounding knife
Fv — load switch fuse combination electrical module
V sl—vacuum breaker module
Sl sv - busbar segmentation switch module (load switch)
Sv—busbar segmentation switch module (vacuum switch)
Sv is always with the bus lift module
B be—busbar grounding module
M-meter module
Product structure characteristics
1. Fully sealed and fully insulated design: H(L)6-24 All live parts are sealed in a box welded by 304 stainless steel plate, which is filled with working pressure of 1.4bar.
2. Sf6 gas, protection class ip67.It is suitable for installation in areas with high humidity and dust pollution. It is especially suitable for mines, box-type substations and any places where surface flashover is easy due to air pollution.
3. The product is fitted with a din47636-compliant bushing that is connected to the cable via a fully insulated, fully sealed, shielded cable gland.
4. High reliability and personal safety: all live parts are sealed in the SF6 air chamber; the air chamber has a reliable pressure relief passage and passed the internal fault arcing test of 20kA/0.5s;
5. The load switch and grounding switch are three-position switches that simplify interlocking with each other.There is a reliable mechanical interlock between the cable compartment cover and the load switch to prevent accidental entry into the charging interval.
6. Maintenance-free and long life cycle: The product has a design life cycle of 30 years. During the product life cycle, the main switch does not need to be maintained.The annual air leak rate of the product is ≤ 0.1%.
7. Compact structure: All modules except the air-insulated metering cabinet and PT cabinet are only 350mm wide.The cable joints of all units are of the same height to the ground, which facilitates on-site construction.
8. H(l)6-24 Configurable intelligent control unit (optional) provides effective protection, remote control and monitoring systems, and supports automation of the power distribution system.
9. H(L)6-24 provides two protection methods for the transformer: load switch fuse combination and circuit breaker with relay protection.Load switch fuse combination for 1600kVA.
And the following transformers, and circuit breakers with relays can be used for transformer protection of various capacities.
10. Environmental protection: The development of h(l)6-24 is not only from the product itself, but also from the production process to the environmental protection of the switch for lifelong operation.All materials are selected to be environmentally friendly materials.
With a zero-leakage cleaning process, the product is sealed for life, and 90% - 95% of the material is recyclable after the end of the product life cycle.
Use of environmental conditions
