5. The monitoring device of the high-speed railway box type substation according to claim 1, wherein the double fuses, the transformer and the high-voltage load switch protection fuses on the assembling block are assembled firstly, then the assembling block is moved to be fed into the box body, and cables of the double fuses, the transformer and the high-voltage load switch protection fuses are long enough to ensure that the cables of the double fuses, the transformer and the high-voltage load switch protection fuses cannot be adverse to the connection of the double fuses and the transformer and the high-voltage load switch protection fuses during the movement of the assembling block;
and the assembling block is also provided with a ferrule.
6. The monitoring equipment of the high-speed railway box-type substation according to claim 1, characterized in that, the monitoring equipment of the high-speed railway box-type substation still includes an L type and colludes the piece, the L type collude the piece and include colluding portion and plastics column spare, collude the portion and be the column, its vertical one end of locating the plastics column spare, the L type collude the piece and stretch into the holding port on the box, the holding port is the non-perforating hole, and its port has open one side on the box, still is equipped with the hole of accomodating on the box at the place of holding port, accomodate the hole and collude a portion adaptation, when the plastics column spare stretches into in the holding port, collude the portion and just be in accomodating the hole.
7. The monitoring device of the high-speed railway box type transformer substation as claimed in claim 1, wherein the box body is provided with an exhaust port, and the double fuses, the transformer and the high-voltage load switch protection fuses are arranged in the box body, so that the double fuses, the transformer and the high-voltage load switch protection fuses cannot be prevented from heat accumulation during operation, and are not beneficial to the operation of the double fuses, the transformer and the high-voltage load switch protection fuses, and therefore the exhaust port is required to be arranged, so that the temperature-rising air flow in the box body can be discharged.
8. The monitoring equipment of the high-speed railway box type transformer substation of claim 1, wherein an exhauster is arranged in the box body, the exhauster is positioned on the side of the assembly block farther from the opening, the exhauster aligns with the assembly block to supply air, the exhauster aligns with the assembly block, and the assembly block is provided with a fuse for protecting the double fuses, the transformer and the high-voltage load switch.
