Abstract
The invention relates to a high-voltage integrated protector shell with double connected layers. The high-voltage integrated protector shell consists of a top shell, an internal partition board and a base shell which are plugged with one another. The high-voltage integrated protector shell with the double connected layers adopts a layered structure; a power supply is separated from a circuit board, and is isolated in a space around which metals are arranged, so that electromagnetic interference to the circuit board can be greatly reduced; and the space is large enough to provide the enough space for further adding a backup power supply.
Description
Technical field
The present invention relates generally to a kind of shell of high pressure comprehensive protection device, relates in particular to double-deck interconnection system high pressure comprehensive protection device shell.
Background technology
Along with the lifting of coal mining ability and the increase of Coal Production accident, the safety in production problem in colliery more and more is subjected to people's attention.The start and stop state of the function emphasis of traditional coal mine safety monitoring system environmental parameter, capital equipment under monitor well and major parameter carry out functions such as separating brake and lock operation automatically under adventurous situation.This system has produced important effect to Safety of Coal Mine Production, along with science and technology development, the automatization level in colliery improves year by year, many electromechanical automatic subsystems have been formed, these subsystems have remedied the few deficiency of coal mine safety monitoring system function, these subsystems are through the operation of long-term industry spot, proved that subsystem performance is stable, reliably, therefore the condition that has possessed further raising automatization level, realizes colliery power-equipment intellectuality, integrated, automation control, the integrated management level of raising equipment is the modern inevitable requirement in current colliery.The underground power supply used centralized control system in colliery is the direction of the forward position development of present colliery automation, and the transformation and the upgrading of this system all realized in a lot of collieries, and the primary problem that solves is exactly the replacing of old high pressure comprehensive protection device in the transformation process of system.Because the many and specification disunity of the manufacturer of the high pressure comprehensive protection device on the present domestic market; caused the protector of each manufacturer production that the connector of different model and the wire size of different definition are all arranged; brought very big trouble in transformation process, for the replacing protector; even need use electric iron in the down-hole, under highly gassy mine, increased certain danger.In the design of comprehensive protection device in the past power supply and circuit board be put together in the middle of without any quarantine measures; this just makes the interference signal in some power supplys can interfere with some acquired signal or control signal, has reduced the stability and the anti-interference of integrated protection phase integral body.
Summary of the invention
In order to solve some unfavorable problems of existing protector outer casing; the invention provides a kind of double-deck interconnection system high pressure comprehensive protection device shell; before and after having adopted, this invention connects and hierarchy up and down; not only making is easy to use in transformation process has also increased the whole interference free performance of comprehensive protection device, has improved stability.
The technical solution adopted for the present invention to solve the technical problems is: this bilayer interconnection system high pressure comprehensive protection device shell comprises top shell, air plug, internal partition, circular hole, top board, terminal board, base shell, this bilayer interconnection system high pressure comprehensive protection device shell is pegged graft mutually and is constituted by top shell, internal partition, base shell three parts, described top shell is the cavity of a bottom opening, the top of top shell is provided with an air plug, is used to connect the inside and outside cable connection of protector outer casing; Described internal partition is a vertical steel plate, in order to separate circuit board and power panel, side at internal partition is provided with a circular hole, the cable of being convenient between circuit board and the power panel connects, top at internal partition, transverse weld has a horizontal top plate, and described top board surface is provided with four terminal boards, in order to satisfy different current terminals; Described base shell is an open-topped cavity, coincide with internal partition and pegs graft, in order to place circuit board and power panel respectively; When power supply during in operate as normal; can produce a large amount of electromagnetic interference; especially electromagnetic interference is more severe under the situation of power quality difference; this bilayer interconnection system high pressure comprehensive protection device shell adopts hierarchy; power supply and circuit board are separated; power supply is independent in a space, is that metal can reduce greatly that enough increasing back-up source greatly from now on provides enough spaces to the electromagnetic interference of circuit board and space all around entirely.
Beneficial effect of the present invention: this bilayer interconnection system high pressure comprehensive protection device shell adopts hierarchy; power supply and circuit board are separated; power supply is independent in a space, is that metal can reduce greatly that enough increasing back-up source greatly from now on provides enough spaces to the electromagnetic interference of circuit board and space all around entirely.
