Embodiment Construction

[0035] Below, refer to the attached Figure 1-7 , describing a locking mechanism according to a preferred embodiment of the present invention. First, refer to figure 1 , figure 1 Shows the interior of the RMU with the decorative panels removed. On the front panel 1 of the ring network cabinet, a keyhole-shaped operation opening is usually provided, figure 1 There are three keyhole-shaped openings shown in , wherein the uppermost operating opening 10 is the opening for operating the grounding knife switch, an operating rod (not shown) can be inserted into the operating opening 10, and is connected with the operating grounding knife switch ( (not shown) operating mechanism (not shown), thereby operating the grounding knife switch, so that the ring main unit is grounded.

[0036] As mentioned above, in order to prevent accidents such as short circuit caused by operating the grounding knife switch when the incoming line side is charged, a locking mechanism 100 is provided in t...

Abstract

The invention discloses a locking mechanism for a ring main unit and a ring main unit. The ring main unit includes a control panel. The control panel is provided with an operating opening for operating a grounding knife switch. The locking mechanism includes: a guide rod. , the guide rod is movable between a locking position blocking the opening and an unlocking position allowing the opening; and a driver capable of placing the guide rod in the desired position in response to a predetermined state of the ring main unit. the locked or unlocked position. Through this locking mechanism, the opening of the grounding knife switch can be locked when the incoming line side, the outgoing line side, or both of the ring main unit cabinet are electrified, thereby improving the safety of the ring main unit cabinet.

Description

technical field [0001] The present invention relates to a ring network cabinet, and in particular to a locking mechanism of the ring network cabinet, which can prevent the operation of the grounding switch when the incoming line of the ring network cabinet is electrified. Background technique [0002] In order to improve the reliability of power supply and enable users to obtain power from two directions, the power supply network is usually connected into a ring. This power supply method is referred to as the ring network power supply. In power distribution systems such as industrial and mining enterprises, residential quarters, ports and high-rise buildings, the high-voltage circuits are usually controlled by load switches or vacuum contactors, and are equipped with high-voltage fuses for protection. The system is usually powered by a ring network, and the high-voltage switchgear used is generally called a ring network cabinet. [0003] The ring network cabinet is usually...
