Abstract
The utility model discloses an intelligent test platform for testing the protection performance of an explosion-proof appliance, comprising an externally-connected test device, a measuring end formed by various sensors, a signal lamp and a digital instrument, a control end formed by a relay and a contactor, a signal converter, and a computer used for data processing and program control, wherein the signal transmission relation of above various components is that: a analog signal of the measuring end is transmitted to the signal converter, the signal converter converts the analog signal into a 485 digital signal and transmits the 485 digital signal to the computer, the computer determines and stores test data transmitted from the signal converter, a control signal is transmitted to the signal converter in the manner of the 485 digital signal, and the control signal is transmitted from the signal converter to the control end, thereby remotely controlling test process. The test platform is widely suitable to the detection acceptance check in a mining electric appliance manufacturing plant, a coal mine electrical maintenance workshop and an equipment management department.
Description
Technical field
The utility model relates to the explosion-proof electric apparatus testing table, relates in particular to explosion-proof electric apparatus protective value testing table.
Background technology
Electrical equipment at underground mine use all is explosion-proof electric apparatus; For example high-voltage vacuum distribution equipment, high-low pressure vacuum feed switch, high-low pressure vacuum electromagnetic starter (multi-loop combined switch, soft starter, fan switch), hand drill etc.; No matter be new-product development or the electrical equipment ground maintenance of ore deposit side; All need make an experiment projects such as for example overvoltage/undervoltage, overload, short circuit, the phase failure, earth leakage search/lockout, electric leakage are moved, 1K leaks electricity actuation time, the test of electric leakage cancellation ratio to protective value.Traditional protective can test unit be arranged and is disperseed, manual operation test, can not far control, TDR can not form preservations automatically, transmission and printing, and ten minutes is inconvenient.Be sought after a kind of comprehensive intelligentized testing equipment.
Summary of the invention
The explosion-proof electric apparatus protective value intelligence testing table of the utility model is on above-mentioned traditional experiment stylobate plinth, utilizes computer program controlled technology, carries out functional control in conjunction with relay and contactor, and keeps former manually operated function.
A kind of explosion-proof electric apparatus protective value intelligence testing table; It comprises external testing equipment; The measuring junction of being made up of all kinds of mutual inductors, signal lamp and digital instrument reaches the control end of being made up of relay and contactor, it is characterized in that, it also comprises signal converter and is used for data processing, programme controlled computing machine; The analog signal transmission of measuring junction is given signal converter; Signal converter converts 485 digital data transmission to and gives computing machine, and the test figure that computing machine transmits signal converter is collected and judged storage, and can control signal be transferred to signal converter through 485 digital signalings; Signal converter is transferred to control end, thus far distance controlled test process.
The good effect of this testing table is; Testing table is easy to operate; It is convenient manually to automatically switch; Pilot project is complete, and form test report automatically, preserve and can the surf the Net transmission and printing of control safety far away, test figure can suit be checked and accepted in the detection of mining electric appliances plant, colliery electric repair and equipment control department when operating automatically.
Description of drawings
Fig. 1 is the block diagram that the utility model embodiment forms structure.
Embodiment
As can be seen from Figure 1; The composition structure of explosion-proof electric apparatus protective value intelligence testing table; The control end that measuring junction that it comprises external testing equipment, be made up of all kinds of mutual inductors, signal lamp and digital instrument and relay and contactor are formed is characterized in that it also comprises signal converter and is used for data processing, programme controlled computing machine; The analog signal transmission of measuring junction is given signal converter; Signal converter converts 485 digital data transmission to and gives computing machine, and the test figure that computing machine transmits signal converter is collected and judged storage, and can control signal be transferred to signal converter through 485 digital signalings; Signal converter is transferred to control end, thus far distance controlled test process.
The method of manipulating of this testing table is:
The first step: the relevant position that the measuring junction and the control end of testing table is installed and connected in explosion-proof electric apparatus to be tested;
Second step: when manual, according to operated in accordance with conventional methods;
The 3rd step: when automatic, double-click computer desktop, open autotest program bag test interface, select product category;
The 4th step: input setting current, main circuit voltage, censorship unit, product type and numbering;
The 5th step: click interface start and stop button, see working power, test current, leak resistance off, gather electric current, voltage, actuation time automatically, get into test, and judge test findings automatically;
The 6th step: after all test events are accomplished, click " generation form ", at last laboratory report deposit or print safe then withdrawing from.
