Abstract
The invention discloses an anti-corrosion hydropower station monitoring device which comprises a cabinet body (1), wherein printed circuit boards (2) and electronic components (3) welded on the printed circuit board (2) are arranged in the cabinet body (1), a protective layer is coated on the surface of a welding part of the printed circuit boards (2) and the electronic components (3); and two or more printed circuit boards (2) are connected with plugs through connectors when connected. In the technical scheme of the invention, the protective layer coated on the surface of the welding part prevents welding spots from being corroded; and the printed circuit boards are connected through the connectors, have good contact property, and are reliable and durable.
Description
Technical field
The present invention relates to a kind of Monitoring and Control System for Hydropower Station, be specifically related to a kind of anticorrosion hydroelectric station supervising device.
Background technology
Monitoring and Control System for Hydropower Station is the basis with modern computer, network technology, automatic technology and information technology, is applicable to the various hydroelectric plant of process control.
Comprise cabinet in the said system, be provided with printed circuit board (PCB) in the cabinet, electronic component is welded on the printed circuit board (PCB), and the problem of its existence is that weld is corroded easily, has a strong impact on the life-span of electronic component.
In addition, when one or several printed circuit board (PCB) is formed a functional unit, directly connect with lead between the printed circuit board (PCB), shortcoming is that contact is poor between the printed circuit board (PCB), is not durable.
Summary of the invention
The present invention has overcome the deficiency of prior art, provides between a kind of printed circuit board (PCB) contact performance good, durable reliable, and has the hydroelectric station supervising device of anti-electronic component corrosion.
For solving above-mentioned technical problem, the present invention adopts following technical scheme:
A kind of anticorrosion hydroelectric station supervising device comprises cabinet, is provided with printed circuit board (PCB) in the cabinet and is welded on the electronic component on the printed circuit board (PCB), the surfaces coated matcoveredn of the weld of said printed circuit board (PCB) and electronic component.
In order better to realize the present invention making further technological improvement below:
As preferably: at least two of said printed circuit board (PCB)s are connected with plug through connector between the printed circuit board (PCB).
Compared with prior art, the invention has the beneficial effects as follows:
In the technical scheme of the present invention, electronic component is welded on the printed circuit board (PCB), and the weld surface scribbles layer protective layer, is corroded to prevent solder joint.
When one or several printed circuit board (PCB) is formed a functional unit, connect with connector between the printed circuit board (PCB), its contact is good, reliability and durability.
Description of drawings
Fig. 1 is a structural representation of the present invention.
Wherein, the pairing name of the Reference numeral in the accompanying drawing is called:
The 1-cabinet, 2-printed circuit board (PCB), 3-electronic component.
Embodiment
Below in conjunction with Figure of description the present invention is done to specify further, but execution mode of the present invention is not limited thereto.
As shown in Figure 1, a kind of anticorrosion hydroelectric station supervising device comprises cabinet 1, is provided with printed circuit board (PCB) 2 in the cabinet 1 and is welded on the electronic component 3 on the printed circuit board (PCB) 2, the surfaces coated matcoveredn of the weld of said printed circuit board (PCB) 2 and electronic component 3.
When above-mentioned printed circuit board (PCB) 2 is two or polylith, forms a functional unit, pass through connector between the printed circuit board (PCB) 2 and be connected, do not allow between printed circuit board (PCB) 2, directly to connect with lead with plug; All elements and measuring point are provided with mark clear, anti-cleaning on the printed circuit board (PCB) 2, to show element number and group piece number.
Claims (2)
1. anticorrosion hydroelectric station supervising device; Comprise cabinet (1); Be provided with printed circuit board (PCB) (2) in the cabinet (1) and be welded on the electronic component (3) on the printed circuit board (PCB) (2), it is characterized in that: the surfaces coated matcoveredn of the weld of said printed circuit board (PCB) (2) and electronic component (3).
2. anticorrosion according to claim 1 hydroelectric station supervising device is characterized in that: (2) at least two of said printed circuit board (PCB)s are connected with plug through connector between the printed circuit board (PCB) (2).
