Description
技术领域 technical field
本实用新型属于电网安全控制短引线保护技术领域，具体涉及一种户外组合CT二次接线盒的防雨装置。 The utility model belongs to the technical field of electric network security control short-lead protection, in particular to a rainproof device for an outdoor combined CT secondary junction box.
背景技术 Background technique
目前传统的户外组合电器CT二次接线盒在使用过程中，用来穿二次电缆的圆孔正好开在接线盒的上平面上，这样容易造成雨水顺着垂直布置的二次电缆流入到接线盒内，从而导致设备或电网事故。在CN 202177640 U中公开了一种电力仪表的封闭壳体，包括端子进出端、封闭式的金属外壳、控制面板及板件卡槽，控制面板与接线端子进出孔分别安装在金属外壳相对的两侧，板件卡槽成对固定在金属外壳内部，所述成板件卡槽的位置分别位于控制面板与接线端子进出孔所在的两侧。它将现有技术中的塑料壳体改金属壳体，金属外壳四面密封，电子仪表设置在本实用新型封闭壳体中，达到了防水、防尘、防EMC4 级静电的特殊要求，金属壳体也有利于散热，有效的解决了电力仪表的板件散热问题，满足了特殊场合下电力仪表的安全使用，但是其制作成本高，装卸不方便，所以需要一种结构简单、价格低廉、防雨效果好的装置。 At present, during the use of the traditional CT secondary junction box of outdoor combined electrical appliances, the round hole for passing the secondary cable is just opened on the upper plane of the junction box, which will easily cause rainwater to flow into the wiring along the vertically arranged secondary cables. box, resulting in equipment or grid failure. In CN 202177640 U, a closed casing of an electric power meter is disclosed, which includes a terminal inlet and outlet, a closed metal casing, a control panel and a board slot. On the side, the board slots are fixed in pairs inside the metal casing, and the positions of the board slots are respectively located on the two sides where the control panel and the terminal access holes are located. It changes the plastic shell in the prior art into a metal shell, and the metal shell is sealed on all sides. The electronic instrument is arranged in the closed shell of the utility model, which meets the special requirements of waterproof, dustproof, and EMC4-level static electricity. The metal shell It is also conducive to heat dissipation, which effectively solves the problem of heat dissipation of the board of the power meter and meets the safe use of the power meter in special occasions. However, its production cost is high and it is inconvenient to assemble and disassemble. Therefore, a simple structure, low price, and rainproof Good device.
