Description

Technical Field

[0001] The utility model relates to the field of power distribution cabinets, in particular to a low-voltage power distribution cabinet with upper outlet lines and anti-drip water. Background Art

[0002] In low-voltage switchboards, the structure of the distribution cabinet will change with the changes in the environment. In the low-voltage feeder cabinet with upper outlets, some dripping environments will cause water to enter the distribution cabinet, resulting in damage to the distribution cabinet and the risk of electric shock; this will require the traditional distribution cabinet structure to be modified:

[0003] If the existing low-voltage distribution cabinet adopts top outlet, the top cover plate has holes for cables. If the cable and the hole do not match, the gap is too large or the sealing is not good, the protection level will not be achieved and water will enter.

[0004] Another point is that when the dripping water accumulates to a certain amount, the accumulated water on the top will flow into the cabinet along the edge of the top of the cabinet because there is no circulation channel. Utility Model Content

[0019] In order to make the technical problems, technical solutions and beneficial effects solved by the utility model more clear, the utility model is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.

[0020] Please refer to Figure 1-4 As shown, a drip-proof low-voltage power distribution cabinet with top outlet includes a cabinet body, a top cover plate 1 is obliquely arranged on the top of the cabinet body, and a side wall surface of the cabinet body is extended out from the side of the top cover plate 1 that is inclined downward, and a water pipe quick connector 2 is provided on this side, and the water pipe quick connector 2 is connected to a water pipe 3.

[0021] Specifically, the top cover plates 1 are provided in plurality, and two adjacent top cover plates 1 are provided with waterproof clips 4 at their edges.

[0022] Specifically, the top cover plate 1 is provided with a plurality of cable glands 5 .

[0023] Specifically, the cabinet body lifts up the top cover plate 1 through the lifting ears 6 .

[0024] Specifically, a water guide groove 7 is provided in the top cover plate 1 .

[0025] According to the purpose of low-voltage cabinets, standard low-voltage cabinets can be divided into incoming cabinets, contact cabinets, compensation cabinets, feeder cabinets, etc. Since the number of feeder cabinets is the largest cabinet type, the top frame transformation this time uses the feeder drawer cabinet as the transformation model for detailed description. The transformation of other types of low-voltage cabinets is similar;

[0026] The standard feeder cabinet structure is assembled from columns and beams to form the skeleton of the low-voltage cabinet, and then assembled into a standard feeder cabinet with a width of 600 mm, a depth of 1000 mm, and a height of 2200 mm, by adding 4 sealing plates on the left and right sides, a rear door plate, a mounting bracket, an insulating busbar clamp, a drawer in front of the cabinet, and a partition.

[0027] Generally, the top of the power distribution cabinet needs to be routed first and heat dissipated second. Both of these require routing holes and heat dissipation holes, which are contradictory to the power distribution cabinet's ability to prevent dripping. To solve the above two problems, this patent adds a top cover similar to a water storage tank on the basis of the original 2200mm high low-voltage cabinet. This cover is made of stainless steel sheet, and is bent upward on all sides to form a 90-degree folded edge with a height of 50mm. The gap formed at the overlap of the two folded edges after bending is processed by welding technology, so that this top frame can store a certain amount of water without leaking. The rear half of this newly added top cover has a waterproof gland installation hole that matches the cable, and a gland for the upper cable outlet is installed. The gland ensures the sealing of the cable and the cable hole when the cable passes through the gland when entering and exiting the top plate of the low-voltage cabinet, and plays a good role in waterproofing and fixing the cable. There is a waterproof rubber plug inside the gland, and the waterproof effect can also be achieved when no cable is passed through.

[0028] The newly added cover plate is provided with threaded holes for mounting the lifting ears around it. The lifting ears play the role of supporting and fixing the newly added waterproof top cover plate, and also play the role of bearing the weight of the lifting cabinet. Therefore, the lifting ears are made of M12 threaded stainless steel, fixed on the cabinet frame at the bottom, and the top cover is made of threaded holes and waterproof rubber washers to play a waterproof role;

[0029] After the newly added cover is fixed and installed according to the above holes, the left, right and back sides are flush with the edge of the cabinet, and the front side extends out 80mm from the edge of the cabinet; this solution can prevent vertical dripping from falling on the operating handle protruding from the front of the cabinet; in order to make the accumulated water flow to the front of the cabinet, the back of the cover is higher than the front of the cabinet by a certain angle, so that the plate is tilted forward, and the accumulated water will flow to the front of the cabinet, and a small water guide groove is pressed at the edge of 80mm extending from the front of the cabinet, and a water flow hole is opened at one end of the water guide groove; this hole is used with a water pipe quick connector and a transparent rubber water guide pipe to guide the accumulated water to the cable trench at the bottom of the cabinet; this rubber water pipe is vertically pre-buried in the cavity of the cabinet side column until it reaches the cable trench or the water storage device on the ground;

[0030] The original top cover of the standard cabinet is still installed normally, and the original cover has wire holes and ventilation holes on it, which can ensure the protection level and ventilation effect of the cabinet; the vertical distance between the above-mentioned new cover and the original top cover is about 125mm, so this solution is only 125mm higher than the standard cabinet, which basically does not affect the size of the cabinet; considering that the low-voltage cabinet is often composed of several or more of the above-mentioned incoming cabinets, contact cabinets, compensation cabinets, and feeder cabinets, and the cabinets are arranged in a row; after all the cabinets are modified according to this solution, the newly added top covers of each cabinet are close together, which will form a tiny gap, which may cause a small probability of dripping and leakage, so add a U-shaped card strip on this gap, buckled on this gap, to prevent water from entering the gap;

[0031] Electrically, this feeder cabinet is a standard drawer cabinet. The back of the drawer is equipped with a bus channel for the installation of vertical busbars. The bus channel is equipped with busbar clamps to fix the clamped three-phase vertical busbars. The three-phase vertical busbar is connected to the horizontal power supply main busbar on the top of the cabinet. The vertical busbar is connected to the primary plug-in of each drawer, and power is provided to each drawer through the primary plug-in. Each drawer unit is equipped with a circuit breaker, current transformer, primary and secondary plug-ins, indicator light multi-function instrument, fuse, etc.

[0032] The technical effect of this scheme is

[0033] The first is to simply transform the top of the traditional distribution cabinet, retaining the original top cover with ventilation holes to ensure the original protection level and ventilation effect; the stainless steel waterproof top cover added by the transformation can fundamentally solve the problem of vertical dripping of the distribution cabinet: 1. The cover is tilted in front, and the design of the water guide groove and water guide pipe can prevent continuous dripping from causing water accumulation on the top of the cabinet, and the accumulated water flows into the cabinet along the top edge; 2. The high protection level cable gland can achieve a very high protection level after being matched with the cabinet top plate and cable, especially to prevent the cable of the top inlet and outlet from passing through the cable hole, resulting in gaps between the cable and the hole causing leakage;

[0034] Secondly, the newly added top cover plate is easy to install, simple to process, and can be mass-produced. When the electrical cabinet is supplied, it can be installed according to the actual needs of the user. If the distribution room has a harsh environment with dripping water, this top cover plate and related accessories will be added. After installation, only the cabinet height is increased by 125mm, and the other dimensions remain unchanged, which can adapt to the installation space of the entire distribution room. If the distribution room environment does not have a dripping environment, this accessory can be omitted or removed.

[0035] The above description is only a preferred embodiment of the present application and is not intended to limit the scope of implementation of the present application. Other principles and basic structures that are the same or similar to those of the present application are within the protection scope of the present application.
