Specific embodiments of the present disclosure are described in detail below with reference to the accompanying drawings.

Fig. 1 is a schematic diagram showing the internal structure of a transformer cabinet according to the present invention. As shown in fig. 1, the present invention provides a transformer cabinet, which may include a cabinet body 1 and a fuse 2 and a transformer 3 arranged in the cabinet body 1, wherein the fuse 2 is arranged to receive high voltage electricity through a cable and to transmit the high voltage electricity to the transformer 3, and to disconnect a connection path with the transformer 3 when a current in the cable is greater than a predetermined value. Correspondingly, the transformer 3 may be arranged to receive the high voltage power from the fuse via the cable and to transform the high voltage power to a predetermined low voltage (e.g. a rated voltage for load operation) for output via the cable. For example, the transformer 3 disposed in the cabinet 1 can convert high-voltage power transmitted in a high-voltage power line into low voltage (e.g., 380 v) for use in an oil production line, thereby providing at least one spare power supply line for the oil production line. When the power supply line connected with the load breaks down, the standby power supply line can directly supply power to the load, so that the condition of delaying the construction period is avoided, and the loss caused by the failure of the original power supply line is reduced. Regarding the fuse 2 arranged in the cabinet 1, it can disconnect the circuit when the standby power supply line current is too large, thereby preventing the load damage caused by the fault such as short circuit.

In addition, can also plan the space in the cabinet body 1 through the cable fixed plate, increase the space utilization in the cabinet body 1. The shape of the cable fixing plate 8 can be selected according to actual requirements. In one embodiment, the cable fixing plate 8 has an elongated plate shape with a groove formed at one side thereof. When the cable fixing plate 8 is fixed, the groove area faces the inner wall of the cabinet body 1. In fixing the cable, the cable may be placed in the groove of the cable fixing plate 8. In another embodiment, the cable fixing plate 8 has an elongated plate shape as a whole, and has a zigzag cross-section. When fixing the cable, the cable may be placed in the zigzag turning region of the cable fixing plate 8.

Fig. 2 is a top view showing a transformer cabinet bottom structure according to the present invention. As shown in fig. 2, in one embodiment, the cabinet 1 may include a base 41 for fixing the transformer 3 shown in fig. 1 and two fixing members 42 therein, wherein the base 41 is fixed to the two fixing members 42, the two fixing members 42 are spaced apart from each other at the bottom of the cabinet 1, and the fixing members 42 are fixed to the side walls and the bottom of the cabinet 1, respectively. Because two mounting 42 are fixed with the lateral wall and the bottom of the cabinet body 1 simultaneously respectively, after fixing transformer 3 and base 41 on mounting 42, the lateral wall and the bottom of the cabinet body 1 can all play support and spacing effect to transformer 3, base 41 and mounting 42. Such an arrangement is advantageous over applications where the fasteners 42 are separately fastened to the side walls or bottom, which may be deformed or damaged by excessive tension or pressure applied to the side walls or bottom of the cabinet 1. However, through the utility model discloses a setting about transformer 3, base 41 and mounting 42 can guarantee the bulk strength of the cabinet body 1 and improve the sight and the security of the cabinet body 1.

In the scene of fixing the transformer cabinet on the well cementation vehicle, when the bottom of the cabinet body 1 is fixed, the cabinet body 1 can be placed at a position to be fixed on the well cementation vehicle. Considering that a certain gap exists between the bottom plate of the cabinet body 1 and the well cementing truck, an operator can select a proper operation tool (such as a wrench and the like) to pass through the installation hole to install the bolt between the bottom plate of the cabinet body 1 and the well cementing truck, so that the bottom of the cabinet body 1 is fixed with the well cementing truck. Further, a plurality of shrouding 5 that match with the mounting hole size can be arranged to cabinet body 1 bottom, and wherein shrouding 5 detachably arranges in mounting hole department to shrouding 5 is used for sealing the mounting hole behind cabinet body 1 fixed mounting. Such an arrangement can prevent insects and some large particles from entering the cabinet 1, thereby improving the safety of the devices (e.g., the fuse 2 and the transformer 3, etc.) in the cabinet 1. In addition, the number of the closing plates 5 can be set according to actual conditions and requirements. In an application scenario, a first closing plate 51 and a second closing plate 52 may be disposed at the bottom of the cabinet 1, wherein the first closing plate 51 is provided with an air inlet protection net 511, and the second closing plate 52 is provided with an outlet 521 for passing through a cable.

In application, the air inlet protective net 511 can prevent insects and some large particles from entering the cabinet 1, and at the same time, can perform a certain ventilation effect on the cabinet 1, and can reduce the temperature of devices arranged in the cabinet 1 to a certain extent. The outlet 521 allows a cable used when the transformer 3 is connected to an external load to pass through. Further, the outlet 521 may be provided with a plurality of outlets 521 and uniformly arranged on the second sealing plate 52. Since a plurality of outlet ports 521 are provided, a plurality of different cables can be passed through the different outlet ports 521, respectively, and therefore the diameter of each outlet port 521 is set small. When some of the outlets 521 do not pass through the cable, the outlets 521 can prevent foreign matters from entering the cabinet 1 and also play a certain role in ventilation. Because the air inlet protective net 511 and the outlet 521 are arranged on the first sealing plate 51 and the second sealing plate 52 which can be disassembled, the first sealing plate 51 and the second sealing plate 52 can be disassembled to clean the air inlet protective net 511, and cables can conveniently pass through the outlet 521.

Fig. 3 is a schematic diagram showing a front door of a transformer cabinet according to the present invention, and fig. 4 is a schematic diagram showing a rear door of a transformer cabinet according to the present invention.
