High voltage switch cabinet

KYN28A-12 series of indoor metal armored switch cabinet

  Summary  

KYN28A-12 series of indoor metal armored switch cabinet is set for 3.6~12KV three-phase AC 50Hz single busbar and single busbar system, mainly used in power plant, generator power transmission, power distribution and power system of industrial and mining enterprises of the two substations, power transmission, large high voltage motor starting so, the implementation of measurement, control, protection and monitoring purposes, the cabinet to meet the IEC298, GB3906 and other standards, can prevent the load push-pull circuit breaker, prevent mistakenly charged isolation room, prevent chain function when energized by close grounding switch, can be used with ZN63A or VSK (VS1) vacuum circuit breaker, can VD4 vacuum circuit breaker with ABB and VSM, permanent magnetic circuit breaker series is a superior performance of power distribution equipment.

  Characteristic  

1. the shell adopts imported tibnor, with CNC machining, the multi folding technology, assembly by assembly of international popular, the cabinet has high precision, light weight, high mechanical strength, beautiful appearance, high degree of enclosure protection, up to IP4X;

2. the main electrical components of the switchgear have an independent compartment, the protection level between the compartments is IP2X, the handcart room, the bus room and the cable room all have special pressure relief channels. The cable room has a large space and can be connected with multiple cables.

3. the plan is complete, with the overhead line of import and export, the cable import and export line and other plans, after the arrangement and combination, it can meet all kinds of power supply and distribution requirements of the users.

4. The repair mode in front of this switchgear can make the product be installed back to back or by wall, saving the area, and the post maintenance mode is easy to operate and maintain.

5. All kinds of anti error operation are complete, flexible, safe and reliable.

6. A high voltage live display device and an anti condensation heater can be installed according to the requirements of the user.

7. The handcart is assembled by CNC machine tool with thin steel plate. The mechanism is flexible, reliable, excellent in performance and easy to operate. The same specifications are completely interchangeable.
