The measuring instruments can display various parameters in operation, and some electrical parameters can be adjusted, and prompts or signals can be given for deviations from normal working conditions.

[0003] However, the existing power distribution devices have the problems of large floor space, relatively higher foundation treatment costs, large maintenance requirements, and high subsequent operation and maintenance costs. For this reason, we have introduced a power distribution device for a thermal power plant booster station. Summary of the invention

[0004] The purpose of the present invention is to provide a power distribution device for a thermal power plant booster station, which solves the problems in the background technology that the power distribution device occupies a large area, the cost of foundation treatment is relatively higher, the maintenance volume is large, and the subsequent operation and maintenance costs are high.

[0005] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: A power distribution device of a booster station in a thermal power plant, comprising a distribution box, a support column is fixedly installed on the top of the distribution box, a rainproof roof is fixedly installed on the top of the support column, a sealed door is hinged on the side of the distribution box, a handle is arranged on the side of the sealed door, an exhaust pipe and an air intake pipe are penetrated through the top of both sides of the top of the distribution box, an exhaust fan is arranged in the inner cavity of the exhaust pipe, an air intake fan is arranged in the inner cavity of the air intake pipe, a wire arrangement board is arranged on one side of the inner cavity of the distribution box, an L-shaped wire arrangement hole is opened in the wire arrangement board, a fixing plate is fixedly installed on the rear wall of the inner cavity of the distribution box, a positioning hole is opened on the top of the fixing plate, a wire threading hole is opened on the upper end of the rear wall of the inner cavity of the distribution box, a wire entry hole is opened on one side of the bottom of the inner cavity of the distribution box, and a control box is fixedly installed at the middle position of the other side of the bottom of the inner cavity of the distribution box.

[0006] Preferably, the length of the bottom of the rainproof roof is twice as long as the width of the distribution box, and the number of support columns is two, which are symmetrically installed at two diagonally opposite corners of the top of the distribution box.

[0007] Preferably, the wire inlet hole is located directly below one end of the L-shaped wire arrangement hole.

[0008] Preferably, the bottom of the cable tray and the top of the control box are located at the same horizontal height, and the number of L-shaped cable holes is four, two in each group, and the total number is two groups.

[0009] Preferably, the air outlet end of the air inlet pipe is located in the lower half of the inner cavity of the distribution box, and the air inlet end of the exhaust pipe is located in the upper half of the inner cavity of the distribution box.

[0010] Preferably, the wiring board and the control box are both arranged on the branch line in the inner cavity of the distribution box.

[0011] Preferably, the rainproof roof is an isosceles trapezoid, and a trapezoidal groove is provided at the bottom of the rainproof roof, and two supporting columns are respectively fixedly installed on the top of the inner cavity of the trapezoidal groove.

[0012] The present invention provides a power distribution device for a booster station of a thermal power plant. It has the following beneficial effects:

[0013] (1) The present invention uses an intake fan arranged in the air intake pipe to blow air into the distribution box, and an exhaust fan in the exhaust pipe discharges hot air out of the inner cavity of the distribution box, so that the inner cavity of the distribution box is cold-in and hot-out exhausted, which can reduce the temperature in the distribution box. At the same time, a rainproof roof is arranged to prevent rainwater from entering the distribution box through the air intake pipe and the exhaust pipe in heavy rain weather and causing damage to the circuit inside the distribution box. Compared with the existing distribution box, by eliminating the heat dissipation holes on the side of the distribution box, it can effectively prevent the damage to the distribution box caused by rainwater blowing into the heat dissipation holes due to strong winds in harsh environments with heavy winds and heavy rains, thereby affecting the normal operation of the distribution box and increasing the cost of subsequent operation and maintenance, and effectively solves the problems of large maintenance workload and high cost of subsequent operation and maintenance.

[0014] (2) The present invention arranges the input wires through a group of L-shaped wire arrangement holes through which the input wires pass through the wire entry holes and the wire arrangement plate, arranges the output wires through the positioning holes and wire threading holes on the fixed block, and changes the insertion direction of the output wires so that the input wires pass through another group of L-shaped wire arrangement holes, thereby preventing the phenomenon of line confusion in the distribution box and increasing the air flow range in the distribution box. The neutral and live wires of the input wires and the output wires are isolated through the L-shaped wire arrangement holes and the positioning holes, thereby reducing the degree of damage to the wires when a fire occurs in the wires. Furthermore, by arranging the control box inside the distribution box, the floor space occupied by the distribution device can be reduced, and the control box can also be cooled and protected, thereby solving the problem that the existing distribution device has a large floor space and relatively higher foundation treatment costs.

[0024] The length of the bottom of the rainproof roof 13 is twice the length of the width of the distribution box 1, and the number of support columns 12 is two, which are symmetrically installed at the two diagonal corners of the top of the distribution box 1. The rainproof roof 13 is an isosceles trapezoid, and a trapezoidal groove is provided at the bottom of the rainproof roof 13. The two support columns are fixedly installed on the top of the inner cavity of the trapezoidal groove, and the outlet end of the air inlet pipe 8 is located in the lower half of the inner cavity of the distribution box 1, and the air inlet end of the exhaust pipe 7 is located in the upper half of the inner cavity of the distribution box 1.

[0025] Through the above technical scheme, the power distribution device of the booster station of the thermal power plant blows air into the distribution box 1 through the air inlet fan 15 arranged in the air inlet pipe 8, and the exhaust fan 14 in the exhaust pipe 7 discharges hot air to the outside of the inner cavity of the distribution box 1, and the inner cavity of the distribution box 1 is exhausted in a cold-in and hot-out manner, which can reduce the temperature in the distribution box 1. At the same time, the rainproof roof 13 is arranged to prevent rainwater from entering the distribution box 1 through the air inlet pipe 8 and the exhaust pipe 7 in heavy rain weather and causing damage to the circuit inside the distribution box 1. Compared with the existing distribution box 1, by eliminating the heat dissipation holes on the side of the distribution box 1, it can effectively prevent the damage to the distribution box 1 caused by rainwater blowing into the heat dissipation holes due to strong winds in harsh environments of strong winds and heavy rains, thereby affecting the normal operation of the distribution box 1 and increasing the cost of subsequent operation and maintenance, and effectively solves the problems of large maintenance volume and high cost of subsequent operation and maintenance.

The zero and live wires of the input wires and the output wires are isolated through the L-shaped wire arrangement holes 16 and the positioning holes 5, thereby reducing the degree of damage to the lines when a fire occurs in the electric lines.
