Abstract
The utility model discloses a novel power distribution cabinet, which belongs to the field of power distribution boxes. The power distribution cabinet comprises a box body, an upper clapboard and a lower clapboard, wherein the two clapboards divide the inner cavity of the box body into three cavities, namely an upper cavity, a middle cavity and a lower cavity; three insulated gate bipolar transistor (IGBT) modules are arranged between the upper clapboard and the lower clapboard; three air outlets and three ventilating nets are arranged on the back of the box body; and two air inlets and two ventilating nets are symmetrically arranged on the side faces of the box body. The novel power distribution cabinet has the advantages of good radiation effect, convenience in mounting and maintenance of the IGBT modules, and high working stability.
Description
Technical field
The utility model relates to a kind of novel power distribution cabinet, belongs to the distribution box field.
Background technology
Power distribution cabinet generally all is placed in the adverse circumstances of the many dirt of high temperature, should carry out the dustproof and waterproof design.Traditional power distribution cabinet is because the needs of dustproof and waterproof, and sealed cabinet, broken off the circulation with air.But power distribution cabinet is installed with devices such as a large amount of disconnected containers, capacitor, has produced great amount of heat, if these heats can not distribute in time, just might burn out the element in the power distribution cabinet, even cause the blast of power distribution cabinet, produces serious consequence.
In addition, the abominable outdoor mounted environment of power distribution cabinet also requires the IGBT module firm, stable of wherein installing, and better works to realize the IGBT module, avoids the serious consequence that produces because external force causes the damage of IGBT in the power distribution cabinet.
Summary of the invention
To the problem that above-mentioned prior art exists, the utility model provides a kind of novel power distribution cabinet, and radiating effect is better, is convenient to the installation and the maintenance of IGBT module.
To achieve these goals; The technical scheme that the utility model adopts is: a kind of novel power distribution cabinet, comprise casing, and also comprise upper spacer and lower clapboard; Following three chambeies during two dividing plates are divided into cabinets cavity; Three IGBT modules are installed between the lower clapboard, are provided with three exhaust outlets and ventilation net at the back side of casing, and the side of casing is arranged with two air inlets and ventilation net.
The beneficial effect of the utility model is: radiating effect is better, is convenient to the installation and the maintenance of IGBT module, makes power distribution cabinet work more stable.

Fig. 2 is the side structure sketch map of the utility model;
Fig. 3 is the back structural representation of the utility model.
Among the figure: 1, casing, 2, upper spacer, 3, lower clapboard, 4, the IGBT module, 5, the side of casing, 6, the back of casing, 7, air inlet, 8, exhaust outlet, 9, the ventilation net.
Embodiment
To combine accompanying drawing that the utility model is described further below.
Like Fig. 1, Fig. 2 and shown in Figure 3; A kind of novel power distribution cabinet comprises casing 1, also comprises upper spacer 2 and lower clapboard 3; Following three chambeies during two dividing plates are divided into casing 1 inner chamber; Three IGBT modules 4 are installed between the lower clapboard, are provided with three exhaust outlets 7 and the net 9 that ventilates at the back side 5 of casing, and the side 6 of casing is arranged with two air inlets 8 and the net 9 that ventilates.
Be symmetrical set the air inlet 7 and the net 9 that ventilates in the side 6 of the casing of power distribution cabinet; And three exhaust outlets 8 are set in the back 5 of casing, make that casing is inside and outside to connect that circulation of air is better; Reach better heat radiating effect, avoided casing 1 inner vigour device because the serious consequence of overheated generation; In addition, IGBT module 4 is installed between two dividing plates up and down of box house, solid and reliable, ensured the safety and stability of components and parts in the power distribution cabinet.
