Abstract
The utility model discloses a high voltage cable comprehensive protective device comprising a microcomputer comprehensive protection device, an electric power monitoring instrument, a voltage current transformer and a high voltage vacuum circuit breaker. The microcomputer comprehensive protection device, the electric power monitoring instrument, the voltage current transformer and the high voltage vacuum circuit breaker are connected with each other through electric power cables or communication cables. The voltage current transformer carries out sampling on current and voltage information of a high voltage cable and sends the information to the electric power monitoring instrument. The electric power monitoring instrument transmits monitored data to the microcomputer comprehensive protection device. The microcomputer comprehensive protection device emits protection motion instructions to drive the high voltage vacuum circuit breaker. The device is reasonable in structure, reliable in performance and strong in practicality. The device can provide protection such as overflow, under-voltage, quick-break, open-phase protection, etc. for equipment. According to the device, especially for blasting leakage of the high voltage cable, safety accidents of personnel and the equipment can be timely avoided.
Description
Technical field
The utility model relates to the high-tension cable comprehensive protector that a kind of industrial and mineral equipment uses.
Background technology
Along with continuous maximization and the centralization of China's mine industry exploitation, various extractive equipments have obtained application more and more widely, and the extractive equipment that especially adopts high voltage source to drive has been main force's equipment in each large mine.At present, domestic mine blasting is peeled off exploitation and with rotary drill, power shovel etc., is carried out do mechanization operation in a large number, because these equipment all need to carry power supply with high-tension cable, so equipment rear end long high-tension cable in tow all.High-tension cable is constantly wearing and tearing on ore, and the freezing grade of being exposed to the sun and rain affects, and has serious potential safety hazard.
Summary of the invention
Technical problem to be solved in the utility model is to provide a kind of comprehensive protector for mine high-voltage cable, and this device can carry out comprehensive monitoring to high-tension cable, and multiple protective is provided.
For solving the problems of the technologies described above, the technical scheme that the utility model adopts is: a kind of high-tension cable comprehensive protector, comprise computer integrated protection, electric power monitoring instrument, voltage current transformer and high-pressure vacuum breaker, described computer integrated protection, electric power monitoring instrument, voltage current transformer is connected by electric power cable or communication cable with high-pressure vacuum breaker, voltage current transformer is sampled and sends into electric power monitoring instrument the electric current of high-tension cable and information of voltage, electric power monitoring instrument is transferred to computer integrated protection by Monitoring Data, computer integrated protection sends protection action command and drives high-pressure vacuum breaker.
The utility model has the advantages that: this apparatus structure is reasonable, dependable performance, practical, the protections such as overcurrent, under-voltage, quick-break, phase shortage, overload can be provided equipment, especially for the electric leakage of blowing out of high-tension cable, can avoid in time personnel's device security accident.
Accompanying drawing explanation
Fig. 1 is the utility model system block diagram.
Embodiment
With reference to the accompanying drawings the utility model is described in further detail below.
Referring to Fig. 1, a kind of high-tension cable comprehensive protector, comprises computer integrated protection, electric power monitoring instrument, voltage current transformer and high-pressure vacuum breaker.Described computer integrated protection, electric power monitoring instrument, voltage current transformer and high-pressure vacuum breaker are connected by electric power cable or communication cable.The electrical source of power that provides that described high-tension cable is mine mining equipment is transmitted, its voltage and current is used the situations such as machine utilization or fault to alter a great deal, primary voltage electric current is converted into the measuring voltage current signal of secondary by instrument transformer, secondary voltage electric current is sent into electric power monitoring instrument, electric power monitoring instrument is transferred to computer integrated protection by Monitoring Data, computer integrated protection carries out detecting and making rapidly in real time accurate judgement to the signal of secondary, to various overcurrents, under-voltage, quick-break, phase shortage, the faults such as overload electric leakage drive high-pressure vacuum breaker to protect in time action.Effective assurance equipment and personnel's life security.
