KYN28- 24(15) Armoured removable AC metal- enclosed switehgear

KYN28-24(15) series alternating-current metal-clad and metal-enclosed with draw-able switchgear(hereinafter referred to as “switchgear”) is a complete set of power distribution unit of three- phase single bus and single bus section system of 15kV and AC50(60)Hz.
This switchgear is mainly applicable to power plants, power transmitting of middle and small sized generators,distribution of industrial and mining enterprises, electricity receiving and transmitting of secondary substations,as well as starting of large high-voltage motors, etc, realizes control protection and monitoring.
It has“five preventions”, it prevents on-load pushing or pulling circuit breaker’s handcart, prevents making or breaking circuit breaker by mistake, prevents closing circuit breaker when the earthing switch is at closing position, prevents entering into live compartment by mistake, and prevents closing earthing switch under live condition. It can be equipped with the NV1-24(15) type vacuum circuit breaker developed by our company, it really is an ideal distribution equipment with perfect performances.
It complies with the standards GB 3906, GB/T 11022 and IEC 60298.

The main technical parameters

Product structure performance characteristics

1. Switchgear of 24kV(15)with compact volume Structure of this product is similar to that of mid-set switchgear of 12kV, the product is applicable to systems of 24kV/15kV, need not composite insulation or interphase separator,with outstanding insulation performance.
2. Safe structure, flexible installation This switchgear is composed of cabinet body and mid-set withdrawable part(i.e. handcart) two parts. The cabinet body is divided into four separate compartments, degree of protection of the enclosure is IP4X, and the protection degree is IP2X when compartment doors and circuit breaker chamber door are opened. It has overhead incoming and outgoing lines, cable incoming and outgoing lines and other function schemes, it can become power distribution unit of different schemes and forms after permutation and combination. This switchgear can be installed, debugged and maintained from the front side, so it can be arranged in duplex by means of back-to-back or arranged against the wall, which not only improves its safety and flexibility, but also reduces the floor space.

3.Lightning impulse resistant capacity

4. Various handcarts, convenient operation Framework of the handcart is made up of steel sheets through machining of CNC machine tool. The handcart has good insulation coordination with the cabinet body, with safe, reliable and flexibly mechanical interlocking. It can be divided into circuit breaker handcart, voltage transformer handcart and isolating handcart according to the purposes, handcarts of the same specification are exchangeable absolutely. There are breaking position, test position and working position in the cabinet body for handcart, each position has positioning device respectively that guarantees reliable interlocking, must carry out operation according to the interlocking anti-misoperation process. All handcarts adopt lead screw to rotate to push in or withdraw, it is convenient and flexible to operate, suitable for all kinds of operators on duty. When it is required to remove the handcart from the cabinet body, please use a special transfer car to take it out conveniently, then to carry out inspections and maintenance; it adopts mid-set type, has small volume, is convenient to check and maintain.
