KYN28-24 type metal armoring high-voltage AC enclosed switchgear (hereinafter referred to as switchgear) is a group company in order to meet the need of electric power grid, the absorption of advanced manufacturing technology at home and abroad to design new product development in succession based on the KYN28-12 type switch cabinet.
Into the line, feed and control of KYN28-24 type switch cabinet is particularly suitable for 24KV distribution system. Products are widely used in electric power and large factories and enterprises of medium voltage distribution system.
Switch cabinet since it is the derivative product of KYN28-12 switch cabinet, therefore, has the characteristics of KYN28-12 switch cabinet: simple structure, stable and firm; midship installation; operation is convenient and safe to use.
Switch cabinet is composed of a casing and a casing composed of hand car, add partition success can compartment. VSI-24 circuit breaker is arranged on the handcart, hand by hand car guide rail on the car interior, push the handcart can realize the breaker is composed of mobile isolated position to the working position. On the other hand, pulling the handcart can also achieve the circuit breaker by the working position to the isolated position.
The 2 shell
The shell of switch cabinet by aluminized zinc plate made of. Aluminized zinc plate by CNC punching and multiple bending, adopts the self tapping screws and pull riveting nuts and high strength bolts and.
There, the three door front shell: instrument door, unit room door and a cable chamber door. Behind is the integral sealing plate.
3, the breaker handcart
Circuit breaker handcart is composed of circuit breaker and body composition.
Circuit breaker switch cabinet selection of VS1-24 type vacuum circuit breaker, the relevant technical data see Table 2, table 3.
The body is made of the steel plate hand cart. It consists of a chassis, wheel and door control board.
The chassis is provided with a position switch and linkage mechanism in. The former plays the role of electrical control circuit breaker position, the latter one breaker position mechanical linkage.
The roller is arranged at the four corners of the car body, with the help of wheel rolling on the rail, so the body with the circuit breaker into or withdrawn. At the same time, the installation opening and closing control plate contact box curtain door through the curtain door mechanism in the curtain door on both sides of the car.
The 5.4 compartment
In the switch cabinet shell baffle divides the whole cabinet body is divided into four functional compartments: the circuit breaker chamber (B), a bus chamber, a cable chamber (C) (D) and two control room (A), see Figure 1 for each compartment has its own independent window decompression.
