Description

Technical Field

[0001] The utility model relates to a switch cabinet, in particular to a dual-purpose installation structure of a low-voltage branch unit in an intelligent station area. Background Art

[0002] At present, the status monitoring of low-voltage switch cabinets below the distribution area has not been covered. Abnormal power supply in key units in some regions, such as government agencies, key production enterprises, scientific research institutions and confidential units, often has a very bad impact. In order to reduce this impact, the power department needs to have a quick means to find faults, locate faults and provide comprehensive status information for the above situations, accurately determine the type of fault (including switch failure, synchronous line loss, line aging, component damage, etc.), and then formulate solutions, clarify the deadline for resolution, monitor the emergency repair process, and minimize adverse effects.

[0003] The current power distribution monitoring mainly realizes status monitoring by installing low-voltage branch units. However, due to the differences in the structures of different cabinets, the installation of low-voltage branch units is usually divided into guide rail type and embedded type. The structure is single and the two installation methods cannot be interchanged. Utility Model Content

[0024] Example 1

[0025] like Figure 1-5 The shown dual-purpose installation structure of a low-voltage branch unit in an intelligent substation includes a rectangular shell 1 and an embedded installation component 2. The front end of the shell 1 is provided with an annular step 101. The embedded installation component 2 includes a plurality of panel clips 201. Each panel clip 201 is respectively provided with a first snap-fitting piece 2011. The panel clips 201 correspond to the four side edges of the shell 1. Second snap-fitting pieces 102 matching the first snap-fitting pieces 2011 are respectively provided on the four side edges of the shell 1. In the embedded mode, each panel clip 201 is detachably connected to the second snap-fitting piece 102 on the side edge of the shell 1 through the first snap-fitting piece 2011.

[0026] In the embedded mode (i.e. when it needs to be installed on a panel), the panel mounting ring 3 is first passed through the housing 1 and is in contact with the annular step 101 at the front end of the housing 1. Then, each panel clip 201 is engaged with the second clip 102 on the housing 1 through the first clip 2011, so that the panel clip 201 and the annular step 101 at the front end of the housing 1 jointly clamp the panel mounting ring 3 (such as Figure 6 As shown), at this time, the installation can be completed by installing the panel mounting ring 3 back onto the panel of the cabinet.

[0027] Two adjacent side surfaces of the housing 1 are provided with guide grooves 103 that match the corresponding side edges. The guide grooves 103 extend forward from the rear edge of the corresponding side surface, and the guide grooves 103 are parallel to the side edges. The panel buckle 201 includes two buckle plates 2012. The edges of the two buckle plates 2012 are connected, and the two buckle plates 2012 are 90 degrees apart. Two guide blocks 20121 corresponding to the guide grooves 103 are provided on the two buckle plates 2012. When each panel buckle 201 is installed, the guide blocks 20121 can be matched with the guide grooves 103 to push the panel buckle 201 from the back to the front. At this time, the two buckle plates 2012 correspond to the two adjacent side surfaces of the housing 1. When the panel buckle 201 is moved into place, it can be engaged with the second engaging member 102 on the housing 1 through the first engaging member 2011. The cooperation between the guide block 20121 and the guide groove 103 can limit the panel buckle 201 in the left-right direction and the up-down direction, and the first engaging member 2011 and the second engaging member 102 can limit the panel buckle 201 in the front-back direction.

[0028] The panel buckle 201 also includes a clamping extension block 2013, which extends backward from the rear end of the connection part of the two clamping plates 2012. The first clamping member 2011 is a clamping part set on the clamping extension block 2013; the second clamping member 102 is a long strip-shaped clamping groove opened on the side edge, which is set along the front-back direction, matches the clamping part, and the length of the long strip-shaped clamping groove is greater than the clamping part. According to the thickness of the panel mounting ring, the panel buckle 201 can be moved to different positions, and after moving to the right position, the clamping part is clamped in the long strip-shaped clamping groove.

[0029] The cross sections of the long strip-shaped slot and the engaging portion are both sawtooth-shaped. Each sawtooth in the long strip-shaped slot is a right triangle with a right angle at the front side, and each sawtooth in the engaging portion is a right triangle with a right angle at the rear side.

[0032] In the guide rail mode (i.e. when the installation is required to be carried out in cooperation with the guide rail), the guide rail installation assembly 2' can be first assembled on the housing 1', and then the guide rail clamping piece 201' can be inserted into the guide rail 3' of the cabinet through the guide rail clamping slot 2012' (such as Fig. 9 to complete the assembly.

The guide rail clamping member 201' can be directly fastened to the housing 1' by means of bolts.

[0034] The guide rail mounting assembly 2' also includes a guide rail clamping piece 203', a spring 204' and a connecting rod 205'. A notch is formed on the guide rail clamping piece 203', and the notch matches the shape of the guide rail clamping piece 203'. The connecting rod 205' is connected to the inner end of the guide rail clamping piece 203'. The guide rail clamping piece 203' is connected to the guide rail clamping piece 201' through the connecting rod 205'.
