Definitions
- the present invention relates to a power cable connecting portion, and more particularly to a power cable connecting portion having a retaining function and an energizing function in a plug-in connecting portion.
- the tulip contact method of (a) is by inserting and locking a ring-shaped contact formed by bundling a plurality of finger contacts arranged in a circle with a garter spring with connection terminals fixed to a cable conductor.
- the contact method of the multi-ram band (b) is a conductor connection, and an annular groove is provided on the outer periphery of the connection terminal fixed to the cable conductor, and a conductive spring-like contact (for example, multi-ram) is provided in the groove.
- Band is fitted in the circumferential direction, and the conductor is connected.
- the wedge tightening method in (c) inserts the cable conductor into the conductor insertion hole through the wedge, and the rear end of the wedge It is comprised so that conductor connection may be carried out by tightening the wedge clamp
- the retaining portion in the plug-in connection portion is rich in flexibility, it can easily cope with bending stress applied to the power cable, but it is structurally energized. Since the connection terminal on the male side and the finger contact on the female side are in point contact, the 220 kV class power cable short-circuit current (for example, about 60 kA, about 3 seconds) cannot be handled.
- the diameter of the tulip contact is increased, and as a result, the inner conductor is increased in diameter and the bushing is increased in diameter.
- the contact method of the multi-ram band in (b) has an excellent energization function, but does not have a retention function, and in the case of a large size cable, the tip of the connection terminal bends due to compression of the connection terminal, resulting in a stress cone. Insulation characteristics at the interface between the metal and the bushing may be affected.
- a multi-lamb band which is generally used that is, a multi-layer formed by stamping and pressing from a thin beryllium copper plate.
- the contact method using the ram band has a drawback in that it is inferior in flexibility at the current-carrying part.
- the wedge tightening method reduces the contact area between the cable conductor and the wedge tightening bracket and increases the electrical resistance. There is a problem that it is inferior, and since a wedge is used for conductor connection, there is a problem that the diameter of the plug-in connection part cannot be reduced as follows. In other words, when tightening the wedge by screwing in the wedge clamp, it is necessary to retract the stress cone greatly in order to insert the installation tool and secure the work space. In the case of using a wedge for conductor connection, there is a possibility that a face will be generated when the wedge clamp is screwed in and tightening the wedge. If it adheres to the interface with the stress cone, there is a concern that the insulation performance is lowered and dielectric breakdown is caused.
- the ball lock type plug-in connecting portion includes an inner plug 200 fixed by compression to the tip of the conductor 100a of the power cable 100, and an outer periphery of the inner plug 200.

- a coil spring 700 is provided between the outer plug 400 and the pressing metal 500.
- the inner conductor 300 and the outer plug 400 are locked by pressing the stress cone 800 toward the distal end portion and moving it forward, so that the cable 100 Is prevented from being pulled out. Also, as shown in FIG. 6, by retracting the stress cone 800, the locked state between the inner conductor 300 and the outer plug 400 is released, and the cable 100 can be pulled out.
- the plug-in connecting portion having such a configuration, although the cable can be reliably prevented from being pulled out (having a retaining function), the outer plug 400 is disposed outside the inner plug 200. There is a drawback that the outer diameter of the connecting portion is increased.
