Abstract
The utility model discloses an underground electric transmission and transformation device for mine, which comprises a step-down transformer and a booster transformer, wherein the step-down transformer and the booster transformer are respectively connected to the two ends of a transmission line needing for low voltage, and the output end of the booster transformer is further connected with the step-down transformer used by a power consumption terminal. In the utility model, due to the adoption of a 10KV/400 booster transformer outside a mine, the transmission line has a low voltage of 400V before electric current arrives at positions near a power consumption terminal, so that safety during prospecting can be ensured, and when the electric current arrives at the power consumption terminal, a 400/1000 booster transformer and a 1000/400 step-down transformer are adopted for supplying power to the power consumption terminal, the power supply method ensures that risks caused by high-voltage power supply in the mine can be avoided, the problem of distant-range low power supply voltage can be solved, a normal voltage at the tail end can be ensured, and because the voltage is higher before reaching the terminal, the loss is low and the cost for power supply is lower.
Description
Technical field
The utility model relates to the electric energy transmitting field, especially relates to a kind of power transmission and transformation device.
Background technology
It is that voltage is low that low pressure long distance power supply in down-hole, mine exceeds radius of electricity supply, and equipment can not run well, because of mine locating needs can not adopt high voltage supply again,
The utility model content
The purpose of this utility model is to provide a kind of power transmission and transformation device that solves the problem that voltage is low in the existing long distance powedr transmission.
The technical solution of the utility model is:
A kind of mine down-hole power transmission and transformation device, comprise step-down transformer, it also comprises step-up transformer, connects step-down transformer and step-up transformer respectively at the power transmission line circuit two ends that need low pressure, also is connected with the step-down transformer that uses for electric terminal at the output of step-up transformer.
The utility model is by using the 10Kv/400 step-up transformer outside mine, bus voltage is the low pressure of 400v before near the electric terminal, safety when guaranteeing mine locating, when arriving electric terminal, adopt 400/1000 step-up transformer and 1000/400 step-down transformer that electric terminal is powered, this supply power mode had both avoided adopting the danger of high voltage supply in mine, solved the low problem of remote power-feeding voltage again, the guarantee terminal voltage is normal, and owing to be higher pressure before incoming terminal, loss is little, and power supply input expense is lower.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Embodiment
As shown in Figure 1, the utility model comprises 10Kv/400 step-down transformer 1, the voltage of power transmission line is 400v when long distance is carried, not that high voltage supply can not cause safety problem, enter near the electric terminal of mine at power transmission line after, one 400/1000 step-up transformers 2 are set and link to each other with 1000/400 step-down transformer 3, step-down transformer 3 links to each other with electric terminal again, the voltage that at this moment electric terminal is powered can keep normal voltage 400v, can guarantee the normal operation of equipment.
Adopt this supply power mode both to avoid in mine, adopting the danger of high voltage supply, solved the low problem of remote power-feeding voltage again.
