Description

Technical Field

[0001] The utility model relates to the technical field of electrical switchgear, and particularly relates to a switchgear. Background Art

[0002] Switchgear is mainly used for switch devices related to power generation, transmission, distribution and power conversion, as well as their combinations with control, measurement, protection and regulation equipment, including the general assembly composed of these devices and equipment, as well as associated internal connections, accessories, enclosures and supports.

[0003] On the face cover mechanism of the existing switchgear, the switching of three operating states is realized by the movement of the sliding door, namely the automatic operating state, the manual operating state and the padlock state. The automatic operating state is to perform automatic opening and closing operations on the switchgear through a driving motor inside the switchgear. The manual operating state is to perform manual opening and closing operations on the switchgear through an external handle. The padlock state is generally used when overhauling lines and various equipment. Therefore, at this time, the switchgear must be in the open and power-off state to prevent manual operation of the switchgear.

[0004] However, when the face cover mechanism of the existing switchgear is in the padlock state, if the switchgear is still in the closed state at this time and the operator is negligent, it is very easy to occur the situation of live operation, thus leading to the occurrence of safety accidents. Summary of the Utility Model

[0005] Aiming at the deficiencies of the existing technology, the purpose of the utility model is to provide a switchgear to solve the above problems.

[0006] The technical solution of the utility model is realized as follows: A switchgear includes

[0007] a housing, on one side of the housing is provided with a face cover, on the face cover are respectively opened a padlock hole for a padlock member to protrude and a first hand-operating hole for a hand-operating member to pass through. A sliding door is slidably connected to the back surface of the face cover. A second hand-operating hole is opened on the sliding door, and a locking piece is provided on the back surface of the sliding door. A flange protrudes from the locking piece.

[0008] a closing and opening action mechanism, which is arranged inside the housing. The closing and opening action mechanism includes a driving shaft. When the driving shaft is in the open state, a groove for the flange to enter is opened on the outer wall of the side facing the locking piece of the driving shaft. A jack for inserting and connecting the hand-operating member is provided at one end of the driving shaft close to the face cover.

[0009] Wherein, the locking piece is arranged on one side of the driving shaft and the flange is arranged on the side of the locking piece facing the driving shaft.

[0010] By adopting the above technical solution, when the opening and closing operating mechanism is in the closed state, the groove on the driving shaft faces away from the flange. At this time, if the sliding door is pushed, the top of the flange will contact the outer wall of the driving shaft, thereby preventing the sliding door from sliding and restricting its sliding distance. At this time, the sliding door still blocks the padlock hole, making it impossible for the padlock member to extend from the padlock hole, so locking cannot be achieved; when the opening and closing operating mechanism is in the open state, the groove on the driving shaft faces the flange. At this time, if the sliding door is pushed, the flange will enter the groove, thereby moving the sliding door away and exposing the padlock hole. At this time, the padlock member can be pulled out from the padlock hole to achieve locking; it is ensured that the padlock member can only be pulled out when the switchgear is in a power-off state, thus effectively ensuring the safety of operators and improving safety.
