Problems solved by technology

[0003] At present, the common method for displaying the three-position state signal of the drawer of the low-voltage switchgear is to use the relevant interlocking mechanism to make the drawer three-position mark on the drawer panel, such as Chinese patent CN2561138, in the utility model patent named "three-position positioning display propulsion mechanism", disclosed A three-position positioning and display propulsion mechanism for low-voltage drawer cabinets is proposed. The drawer position can be displayed on the panel of the switch cabinet through the propulsion assembly, the connection locking assembly and the display board, but it cannot electrically transmit the above position signals, and the The mechanical structure is not compact, the location is scattered, the installation is troublesome, the electrical connection is complicated, the modularization cannot be realized, and the versatility is poor

Embodiment Construction

[0028] The features and advantages of the present invention will become apparent from the following detailed description of the preferred embodiment shown in the accompanying drawings.

[0029] see figure 1 , an independent module 1, its cover 11 can be installed on the side corresponding to the drawer 2 or at the bottom corresponding to the drawer 2 according to the specific conditions or specific requirements of the low-voltage switchgear, the cover 11 The material is plastic, which is molded. The sliding cavity 113 is opened on the top of the casing 11, so that the slider 13 can move left and right at the corresponding position. The specific form of the sliding cavity 113 is not limited, for example: disclosed in Figure 10 The sliding cavity 113 is the same as disclosed in the figure 1 The sliding cavities 113 in the two are different in form, but both are for providing a good sliding space for the slider 13 . exist Figure 10 In the case, the cover of the whole casing...

Abstract

The invention is independent module that feature following advantages: 1) can be applied in different type low tension switch cabinet; 2) easy to collect three position state signals for drawer 3) when the displacement of drawer is transformed into switching value, the digital switching value can be transmitted and displayed.

Description

technical field [0001] The invention belongs to a signal collection and transmission device, in particular to a collection and transmission device for three-position status signals of a drawer of a low-voltage switch cabinet. Background technique [0002] With the increasing automation of low-voltage power distribution technology, higher requirements are put forward for the monitoring of various signals. [0003] At present, the common method for displaying the three-position state signal of the drawer of the low-voltage switchgear is to use the relevant interlocking mechanism to make the drawer three-position mark on the drawer panel, such as Chinese patent CN2561138, in the utility model patent named "three-position positioning display propulsion mechanism", disclosed A three-position positioning and display propulsion mechanism for low-voltage drawer cabinets is proposed. The drawer position can be displayed on the panel of the switch cabinet through the propulsion assemb...
