Abstract

The utility model belongs to the technical field of combined electrical appliances, and particularly relates to an indicating structure for displaying three-station switching-on and switching-off processes of a combined electrical appliance. The indication structure for displaying the three-station switching process of the combined electrical appliance comprises a shell, wherein a movable contact seat is arranged in the shell, a movable contact is arranged on the movable contact seat, and a static contact seat is arranged on the outer side of the movable contact. The intelligent monitoring system has the beneficial effects that the problems that the moving direction and the action progress of the contact cannot be intuitively judged in an intelligent monitoring video of the combined electrical appliance are solved under the condition that the current capacity of the switch is unchanged, and the structure is intuitive and reliable and is easy to observe and judge.

Description

Indication structure for displaying three-station switching process of combined electrical appliance Technical Field The utility model belongs to the technical field of combined electrical appliances, and particularly relates to an indicating structure for displaying three-station switching-on and switching-off processes of a combined electrical appliance. Background In the whole power system, along with the continuous improvement of intelligent monitoring technology, the contact position sealed in an SF 6 air chamber (or other environment-friendly mixed gas) is observed through a camera, and the separation and closing states of the contact in the closed air chamber are judged not through the position of a transmission device (mechanism position) or more indirectly through a secondary circuit. To ensure the consistency of the mechanism and the contact state, a double-confirmation loop is designed, but the double-confirmation loop is an indirect judgment, and the contact position is intuitively confirmed to be more accurate by observing the contact position. When the position of the contact is monitored by a video, the contact is in a separated state and a combined state (or a final state) easily distinguished, but in the moving process, the contact is shielded by a shielding cover, the picture of the position of a video interrupt port is as static, the separation process or the combination process cannot be judged by the video, and even if the separation process is known by combining instructions, the separation position cannot be directly judged, and the separation distance is equal to the distance in place. Disclosure of utility model The utility model provides an indication structure for displaying three-station switching process of a combined electrical appliance, which aims to make up the defects of the prior art. The utility model is realized by the following technical scheme: The indication structure for the combined electrical appliance to display the three-station switching-on and switching-off process comprises a shell, wherein a movable contact seat is arranged in the shell, a movable contact is arranged on the movable contact seat, and a static contact seat is arranged on the outer side of the movable contact. The observation window is positioned at the fracture position of the movable contact and the static contact seat in the shell. The intelligent monitoring system has the beneficial effects that the problems that the moving direction and the action progress of the contact cannot be intuitively judged in an intelligent monitoring video of the combined electrical appliance are solved under the condition that the current capacity of the switch is unchanged, and the structure is intuitive and reliable and is easy to observe and judge. Drawings The utility model is further described below with reference to the accompanying drawings. FIG. 1 is a schematic diagram of the front view structure of the present utility model; FIG. 2 is a schematic side view of the present utility model; FIG. 3 is a schematic diagram of the closing state of the present utility model; FIG. 4 is a schematic diagram of the opening state of the present utility model; FIG. 5 is a schematic diagram of the split-combination scale of the present utility model; In the figure, 1 casing, 2 movable contact, 3 movable contact, 4 static contact, 5 observation window, 6 cameras, 7 rectangular recesses, 8 deciliter scaleplates, 9 switch-on sections, 10 switch-on position sections, 11 switch-off sections. Detailed Description The drawings illustrate one embodiment of the utility model. The embodiment comprises a shell 1, wherein a movable contact seat 2 is arranged in the shell 1, a movable contact 3 is arranged on the movable contact seat 2, a static contact seat 4 is arranged on the outer side of the movable contact 3, an observation window 5 for mounting glass is arranged on the shell 1, a camera 6 is arranged on the outer side of the observation window 5, a strip groove 7 is formed in the movable contact 3, a separation and combination scale 8 is arranged in the strip groove 7, and the separation and combination scale 8 consists of a connection section 9, a closing position section 10 and a disconnection section 11. The observation window 5 is positioned at the fracture position of the movable contact 3 and the static contact seat 4 in the shell 1. By adopting the indicating structure for displaying the three-station switching process of the combined electrical appliance, the camera 6 can directly observe the switching state of the contact through the observation window 5 on the shell 1, but the moving contact 3 enters the static contact seat 4, and the relative position between the moving contact 3 and the static contact seat 4 can be ground-observed through observing the moving direction and the position of the switching position section 10 in the middle of the switching scale 8, so as to judge whether the switching of the switch c
