      Product Structure

      JYN1-40.5 (Z) interval remove AC metal-enclosed switchgear structure belonging to the interval, which welded from steel and steel plate bending from the cabinet and handcart two major components. Withdrawable circuit breaker can be classified according to their use, arrester handcart, isolating handcart, "Y" shaped connection voltage transformer handcart, "V" shaped connection voltage transformer handcart, single-phase voltage transformer trolley and the trolley station transformers and other seven, which has ZN85-40.5 vacuum circuit breaker circuit breaker, ZN23-40.5 vacuum circuit breaker and SF6 circuit breaker. Switchgear and trolley dimensions (see Figure 1), the internal structure diagram (see Figure 2)

      Switching equipment according to use separate into several functional units, are described as follows:

      · Housing

      Switchgear enclosure has IP2X degree of protection to prevent a diameter greater than 12 mm inside objects close touch live parts and used part of the movement.

      In addition to the high-pressure intervals door hinges with metal braided copper wire is also used outside the door and the cabinet is connected. In the front and back of the case of the switching devices are equipped with inspection window to observe the operation of the equipment inside the switchgear.

      · Used room

      Lower part of the front of the device switch two doors open, which is the handcart. The upper chamber, separated by an insulating partition between the lower chambers contacts between Roof main bus and provided with a metal bulkhead. There handcart handcart bottom rail, central handcart grounding in both tracks. To prevent condensation heater specialized settings are also located on the right side of the chamber.

      · Main bus and the isolation chamber contacts

      And on a main bus isolation switch contacts in the upper chamber devices. Main lines arranged in a triangular arrangement on the upper post insulator flip. Immediately below the main bus stand for the isolating contacts, which can be a current transformer with a contact, it can be a pillar or wall bushing insulators with contacts, depending on main connection scheme may be.

      · Contact isolation room

      Contact isolation room on the lower contact isolation room, separated by a separator between the two, which in addition to the current transformer for installation or post insulators seat outside contacts, or contact the busbar earthing switch is also located in the chamber .

      · Insulation barrier and insulation valve

      Withdrawable switchgear room between contacts and isolation rooms with cable room, equipped with a partition made of insulating material and the installation of SMC SMC insulation valve on it. Partitions and insulation valves have IP2X degree of protection.

      · Earthing switch

      Grounding switch as a variable element may be trade-offs needed project, when outgoing circuits needed overhaul breaker retreat isolated position, close the earthing switch to ensure safety.

      · Electric display device

      Live shows are variable element, its role in the case of switching equipment is not equipped with a voltage transformer and can directly reflect the charged case of high-voltage feeder lines. So that the grounding switch is closed before the feeder line can be determined in advance whether or not charged.

      · Grounding conductor

      Across the switching device in the entire width direction of the copper ground conductor mounted on the switch in the bottom of the device. The connection between the two, and is equipped with a factory prefabricated devices and connectors can be installed inside.

      · Auxiliary circuit installation equipment

      The upper part of the front of the device is provided with means switching auxiliary circuits equipment meter relay room door and shake the door structure. Both sides of the room there is a small bus control lines through holes and fixed with cable clamp, the left has a small bus terminal group, above and below are equipped to go trough. Meter relay room with doors and high-pressure intervals separated by a partition.

      · Terminal compartment

      Room is located on the right side at the front of the switchgear, auxiliary circuit terminals installed in the central group of the chamber. Top of cabinet lights and switches; provided below ground M12 bolt for auxiliary circuit ground use: The right for users with fixed control cable clamp bracket.

      · Secondary plug (Block)

      Cable trolley and switch between devices are installed in the plug and through the switching device installed in a socket on the trolley car to push forward now to the real. "Hand test position" should plug in. When the handcart Exit "Test Position"; should be unplugged.

      Small Bus

      Switching devices with a small bus terminal group 15, according to the provisions of rationing small bus conductor preparation by the user.

      · Condensation control

      There are large regional variations in humidity or temperature occasion, when switching equipment out of operation, it is possible to produce condensation. Thus installed condensation control within the switching equipment, with the temperature increasing method, such that vapor in the air can not condense.

      Auxiliary loop control cable channel

      Switchgear auxiliary circuit control cable channel (cable channel starting secondary role) located above the relay room, the control cable from the cable channel aligned left or right of the switchgear introduction,

      After the bottom of the bottom of the switching device or terminal compartment left door of the introduction of small channels. The passage through each switching device.

      · Cabinet lighting

      Withdrawable switchgear room with a lamp 220V, 100W lights, lights and switches are mounted above the terminal compartment, the operator must replace the lamp light switch or open the terminal room door before proceeding.
