1, overview

(H) GW13 neutral point switch is used for three-phase AC 50Hz outdoor high voltage electrical equipment, for use in the case of no load closing line of transformer neutral point. The knife in the normal brake position, can provide a consistent with insulation distance safety requirements.

2, the main structure and characteristics

1, the unipolar V double column rotary structure, small occupation area, mainly composed of a base, a supporting insulator, conductive circuit, operating mechanism.

2, the two insulating pillar at a 50 degree angle are respectively arranged on the bearing seat is connected with base, realize to bevel gear meshing transmission. Electric gate is divided into two halves, are respectively fixed on the post insulator, contact in the middle of the two pillars.

3, the actuator moves through a column of a level four drive post insulator rotational 90o, another pillar insulator with umbrella gear and rotate at the same time 90o, then switch to the same side division. The neutral point switch can be equipped with CJ6G perfect improvement of the electric mechanism, also can be equipped with CS17IV perfect improved human body. The human body can also be equipped with new type DSW4 electromagnetic lock. The base unit crank arm, rod, umbrella, the two pillar insulator rotation, with the closing operation, the brake after the insulation isolation fracture enough margin, so as to ensure the safety of;

4, with CJ2 automatic operation mechanism of CS-17G manual mechanism and so on, can be attached to an electromagnetic lock. Actuator output shaft can be rotated 180 degree, positioning device on the mechanism can guarantee the contact and the static contact head at the contact position right or off position.

5, the product has the advantages of reliable performance, safe operation, simple structure, easy installation and maintenance etc..
