Background technology

At present, the colliery with the protective relay of integrated protection and monitoring device based on induction, employing be the design concept of PCS, ACS, CCS, DCS system.Requirement according to " safety regulations in coal mine " the 455th and the 457th; conventional electric power parameters such as the novel intelligent comprehensive protector not only can line voltage detection, electric current, power, electric degree; has the GPF (General Protection False function that rules require; and the communication interface of standard arranged; can realize " four is distant " to the operation conditions of crucial switchgear in the electrical network, for power dispatching automation provides support.And these equipment generally all include only overcurrent, electric leakage and three kinds of basic protection types of ground protection, do not have the network communication ability substantially, can't satisfy the performance requirement of current mining high-voltage switchgear.

The utility model content

The purpose of this utility model provides a kind of colliery integrated protection and monitoring device; mainly solve the technical matters that does not have the network communication ability that induction protective relay exists; the SNP series colliery integrated protection and monitoring device that the utility model is developed; be applicable to 10kV, 6kV and 3.3kV neutral point of electric network ungrounded supply system or neutral point under-compensation earthed system; be the senior multifunctional comprehensive protective device of power switch in confession, the power transformation system, can play monitoring and protective effect electrical network and equipment.Simultaneously, device also has communication interface, can constitute colliery power grid security prevention and control system with other equipment networkings.

The technical solution of the utility model is: a kind of colliery integrated protection and monitoring device, be made up of 3 parts: comprise control module, display, telepilot, display is by the cable link control module, and telepilot and display are by the infrared ray Data transmission.Control module is by the power supply module, the AC sampling module, the CPU module, open into leaving module and operation module composition, the power supply module is connected with the operation module with opening into leaving module with the AC sampling module respectively, AC sampling module output terminal is connected with CPU module input end, the CPU module with open that module is two-way connects into leaving module and operation, the CPU module is by CPU, leave the driving module, open light inlet every driving module, the communication module, A/D converter, memory controller, the liquid crystal display module, low-pass filter and remote control receive module and form, the data that the AC sampling module collects are imported A/D converter through behind the low-pass filter, through A/D conversion back input CPU, handling the back through CPU drives module and is transferred to and opens into leaving module and operating module by leaving, finishing the photoelectricity of switching value isolates and the relay control of export, open into leaving module and operation module data are transferred to CPU, CPU and communication module by opening light inlet again every driving module, the liquid crystal display module, the two-way connection of memory controller; Microcomputer protecting controller adopts the AT96 bus structure, and CPU is the DSP chip Microchip CPUic30F6014A of U.S. Microchip company, and the device power supply is provided by voltage transformer (VT), need not add independent current source.

Beneficial effect is: finish nearly all data manipulation with a slice CPU inside; realized that really bus does not go out chip; the reliability and the antijamming capability of Microcomputer Protection have been improved greatly; because Microchip CPUic peripheral chip is fewer; so the board area that whole hardware design takies is less; price is also lower, and the algorithm programming also realizes easily.Microchip CPUic supports the data transmission of SPI pattern and I2C pattern simultaneously, is convenient to chip capacity and expands.These characteristics make the utility model needing be well suited for the occasion of high resolving power, high sampling rate and supercomputing.Display and body portion from, be convenient to be installed in the various flame-proof switches, Infrared remote controller can be carried out the remote control setting in 10 meters in the distance means installation place, the telepilot shell adopts the hermetically sealed explosion-proof design of metal.The utility model can be the parameters of electric power of underground equipment, operational factor, information about power, out of order reason of equipment state and electric system and fault recorder data send to ground central station, device also can receive orders such as remote control that ground central station sends and involution simultaneously, and carries out data communication.Realize " four is distant " function of high-voltage switch gear, really realize the unmanned of down-hole electric substation.
