Abstract
The invention relates to a transient electromagnetic instrument which comprises a transmitting rack and a transmitting device. The transmitting rack is of a cuboid structure, the top of the transmitting rack is provided with groups of transmitting coils arranged in parallel, the transmitting coils are connected with the transmitting device, and the transmitting coils are wound around the transmitting rack uniformly. The transient electromagnetic instrument has the advantages that multiple transmitting circuits which reach the intrinsic safe requirement are transmitted simultaneously in the same phase by utilizing the principle of magnetic field superposition in the air, parameters and directions of the coils are both identical, the intensity of the transmitting field is increased, the anti-interference capability is greatly enhanced, and the practicality is improved.
Description
Technical field
The present invention relates to a kind of Transient Electromagnetic Apparatus.
Background technology
Transient Electromagnetic Apparatus is the Electric Equipment in Explosive Gas Atmosphere manufactured according to standard GB/T 3836.4-2000, its technical characteristic is, require to connect at the output terminal of battery a certain size resistance, Limited Current thus requirement emissive power be limited in for safety when certain limit reaches actual use.
And when carrying out transient electromagnetic method exploration under ore deposit, the electromagnetic interference (EMI) source under ore deposit is a lot, intensity is considerably beyond the signal of transient field.And existing Transient Electromagnetic Apparatus, by the restriction that transmitter current is too small, depth of exploration is very shallow, and antijamming capability is also very poor.
Summary of the invention
The object of this invention is to provide a kind of Transient Electromagnetic Apparatus, to overcome the above problems.
The object of the invention is to be achieved through the following technical solutions:
A kind of Transient Electromagnetic Apparatus, comprise launcher and emitter, described emitter is rectangular structure, and described launcher is rectangle, and launcher top is provided with the some groups of transmitting coils be arranged in parallel; Described transmitting coil connects emitter, and transmitting coil is wrapped on launcher respectively uniformly.
Beneficial effect of the present invention is: utilize the principle that magnetic field superposes aloft, many groups radiating circuit homophase of intrinsic safety requirement will be reached, launch simultaneously, the parameter equidirectional of coil is identical, they aloft superpose mutually, launching site is forced by force, greatly strengthen antijamming capability, enhance practicality.
Embodiment
A kind of Transient Electromagnetic Apparatus described in the embodiment of the present invention, comprises emitter and launcher, and described emitter is rectangular structure, and launcher is rectangle, and launcher top is provided with the some groups of transmitting coils be arranged in parallel.
Transmitting coil connects emitter, and transmitting coil is wrapped on launcher respectively uniformly; The cross sectional dimensions of described launcher is 1.5 meters × 1.5 meters.
During concrete use, the restriction that Transient Electromagnetic Apparatus requires by intrinsic safety, transmitter current is all very little, is generally all less than 3 amperes, and the principle utilizing magnetic field to superpose aloft, to reach many groups radiating circuit homophase of intrinsic safety requirement, launch, the parameter equidirectional of coil is identical simultaneously, they aloft superpose mutually, launching site is forced by force, actual transmission electric current is reached group number that N × I(N is transmitting coil, I is the transmitter current often organizing transmitting coil).
In theory, find that coil infinitely can be organized number superposition and launch, thus further increase the intensity of signal, and in actual use, by winding volume heavily quantitative limitation in real work, select transmitting coil to be preferably 2-4 group, maximum service efficiency can be reached.
The present invention is not limited to above-mentioned preferred forms; anyone can draw other various forms of products under enlightenment of the present invention; no matter but any change is done in its shape or structure; every have identical with the application or akin technical scheme, all drops within protection scope of the present invention.
Claims (2)
1. a Transient Electromagnetic Apparatus, comprise launcher and emitter, it is characterized in that: described emitter is rectangular structure, described launcher is rectangle, launcher top is provided with the some groups of transmitting coils be arranged in parallel, described transmitting coil connects emitter, and described transmitting coil is wrapped on described launcher respectively uniformly.
