Armour KYN10-40.5 shift type AC metal enclosed switchgear, is to digest, absorb advanced technology at home and abroad, according to the characteristics of the domestic, by the company independently developed a new generation of switch equipment. Technical performance reached and the following exchange above IEC60298<1kV 52kv metal enclosed switchgear and Control Equipment > and GB3906<3 ~ 35kV AC metal enclosed switchgear > standard, with small size, appearance, size and high precision, big breaking short-circuit current, convenient installation, long maintenance cycle, convenient operation and maintenance, the use of safe and reliable many advantages.

purpose

   KYN10-40.5KV switch cabinet, complete set of system of three-phase AC 50Hz indoor metal armoured handcart cabinet and application in power plant, substation system rated voltage of 40.5kV of single busbar and breaking the single bus power system in, as a control, acceptance and distribution of 40.5kV electric network with.

Structure working principle

   KYN10-40.5KV switchgear is a metal armouring structure, protection grade IP2X, cabinet and a handcart two parts. A main wiring plan see Table 8, product dimensions and installation dimensions is shown in Figure 1 and Figure 2.

Note: when an overhead (or cable) line is used as a wire feeder, a ground switch must be removed.

1, the cabinet

   Welded with steel and steel cabinet, mainly divided into four chambers: handcart room, main bus room, grounding switch and outlet chamber, relay room, handcart room is provided with a pressure release channel, hand in hand with car can disconnect the car interior, test position and work location, handcart room with the main bus room, grounding switch and outlet chamber connected by the contact box or contact type current transformer, the contact box is arranged in front of the metal valve, hand car room is arranged at the top of the two socket, another cart room also has to identify the location, hand car heater, the main bus room with insulated bus, between the cabinet and the the cabinet separated by partition and casing, to prevent the expansion of the accident. The switch line and the indoor ground is arranged with the earthing switch and charged display, and switchgear cable inlet and outlet connectors. The relay chamber is installed in the cabinet through the shock absorber for installing the instrument, relay and small bus And so on.

2, hand car

   Handcart frame from steel and steel plates welded together, according to the needs of a wiring scheme, circuit breaker handcart, handcart isolation, voltage transformer hand trolley, lightning arrester hand car, the transformer hand trolley etc., with specifications for the type of hand car has the interchangeability, trolley panel is switch cabinet, equipped with a nameplate, observation window, at the bottom of the handcart with four fixed wheel, when you need to move outside the cabinet, equipped with a steering wheel, before two fixed wheels carry air, also in military vehicles with locking device and labor-saving propulsion device.

3, interlocking

   Reliable misoperation prevention interlocking device are provided the KYN10-40.5 type of switch cabinet, can achieve "prevent misclassification error closing of circuit breaker, prevent loaded hand truck out, prevent with charge grounding switch, prevent the grounding switch is in the closed transmission, to prevent mistakenly charged interval" five prevention requirements. In addition, the isolated handcart and a corresponding circuit breaker handcart is arranged between the electrical get lock, the transformer hand trolley is arranged in the work position cannot load get lock and so on.

Installation arrangement and basic form

1 the installation of switchgear should meet the requirements of the products in the sample:

2. The switchgear is not against the wall installation, layout divided into two kinds of single row layout and double row layout, provided with the bus bridge, as shown in Figure 3 to figure 4 shows. And cabinet fasteners has been attached to the cabinet in the mounting hole, and cabinet installation should be tightened.

3 when the switch cabinet is installed, the track of the hand truck is not allowed to be left hanging, and the ground is close to the ground;

The 4 switch cabinet after the installation of the around the vertical deviation not more than 1.5mm/1000mm;

5 control cable from the switch cabinet at the bottom of the two cable trench introduction, can also be based on user requirements by the end of the switch cabinet;

6 the introduction of the main circuit of the switch cabinet adopts two forms of overhead and cable. The overhead line is required to increase the 800mm deep back cabinet (see chart 1, note 2). The cable terminal box of the import and export is provided by the user.

7 cabinet front corridor should be smooth and bright, so that the hand car to enter;

The 8 switch cabinet installation foundation channel steel and a two loop construction, cable channel in Figure 5, figure 6;

9. Installation of ground foundation construction of switch cabinet shall be in accordance with the "electric power construction and acceptance of technical specifications" to the relevant provisions of. To make the truck drive and reduce dust, operation corridor the terrazzo ground is preferred.
