Embodiment 1

[0024] Such as Figure 1~4 As shown, a marine controllable electromagnetic transmitter based on a three-phase-single-phase matrix converter includes a three-phase generator 1, a matrix converter 3, and a launch bridge 6. The three-phase generator 1, matrix converter 3, and launch bridge 6 are connected in turn to form a transmitter, and the surface of the launch bridge 6 is provided with an anti-corrosion coating.

[0025] The anti-corrosion coating includes the bonding layer ZnNi and the composite layer Cr 2 o 3 , SiC, Zn (H 2 PO 4 ) 2 2H 2 O, edited Cu 2 O, the sticky bottom layer is sprayed to the surface of the launch bridge, and the composite layer is sprayed to the sticky bottom surface. The composite layer is composed of wear-resistant and anti-corrosion powder and antifouling powder, and the wear-resistant and anti-corrosion powder consists of 20 to 35 parts by weight of Cr 2 o 3 powder, 30~40 parts by weight SiC powder, 10~18 parts by weight Zn (H 2 PO 4 ) ...

Embodiment 2

[0035] Such as Figure 1~4 As shown, the present invention selects a common three-phase AC generator 1 with an output frequency of 50 Hz and an output voltage of 380 V to generate the required three-phase AC voltage. The matrix converter 3 is mainly to provide a single-phase bipolar stable voltage to the load to meet the requirements of the electromagnetic detection for the transmitting circuit.

[0036] Matrix converter 3 consists of twelve IGBT S 1 , S 2 , S 3 , S 4 , S 5 , S 6 , S 7 , S 8 , S 9 , S 10 , S 11 , S 12 and twelve freewheeling diodes D 1 、D 2 、D 3 、D 4 、D 5 、D 6 、D 7 、D 8 、D 9 、D 10 、D 11 、D 12 Six bidirectional switches are formed to form three bridge arms. Each bridge arm is composed of four controllable switch IGBTs and four freewheeling diodes D, which are divided into upper and lower parts: S in the upper part of the first bridge arm 1 with D 1 Parallel, S 2 It is connected in parallel with D2, and then the two are reversely conne...

Abstract

A three phase-single phase matrix converter-based marine controlled-source electromagnetic launcher provided by the present invention comprises a three-phase generator, a matrix converter and a launch bridge which are connected orderly to form the launcher. An anti-corrosion coating is arranged on the surface of the launch bridge and comprises an adhesive bottom layer ZnNi and a composite layer of Cr2O3, SiC, zinc dihydrogen phosphate and Cu2O, and the matrix converter is connected with a lightning arrester. According to the present invention, with the matrix converter, the higher current output of a low-power device is realized, and the device is better in heat radiation effect; with the anti-corrosion coating of the launch bridge, the launch bridge can be prevented from being corroded by the seawater effectively, and the normal work of the launch bridge is guaranteed; and with the lightning arrester, the situation that the equipment are damaged due to the lightning strike, and can not work, can be prevented, and the equipment safety is improved.

Description

technical field [0001] The invention belongs to the field of marine controllable electromagnetic prospectors, in particular to a marine controllable source electromagnetic transmitter based on a three-phase-single-phase matrix converter. Background technique [0002] Based on the deteriorating global energy crisis, the exploration and development of seabed resources such as oil and gas and new energy on the seabed have attracted more and more attention from countries all over the world. The huge demand for energy is the driving force for the rapid development of marine controllable source electromagnetic transmitters. The controllable source electromagnetic transmitter has the advantages of relatively low cost and small destructiveness. [0003] The existing technology provides a variety of marine controllable source electromagnetic emission methods, for example, the Chinese invention patent document, a launch method of a marine controllable source electromagnetic exploratio...
