Mineral damage-proof micro vacuum magnetization with motive-proof guard function preset

Rotary induction synchronizer is installed according to the lead type of the rotary induction synchronizer. The rotor of the induction synchronizer and the slip ring on the base plate are connected with the pin of the drill arm, and the stator is connected with the body of the drilling machine. The leads of the rotor winding can pass through the electricity. Brush leads. The rotor winding leads can also be used in the other two ways shown. The rotor and stator of a rotary inductive synchronizer both have 11 gaps as follows: one is to cause an increase in electrical errors, and the other is to change the output electromotive force so that the influence of the electromotive force at the end of the winding becomes greater.

Broken phase lock detection circuit Qin broken phase lock detection circuit principle as shown. ABCJJ”15V Short-Circuit Blocking Detection Circuit Principle socl98KC Microcontroller Module This module consists of soc198KC CPU, address latch 74LS373, program memory 27C64, input output interface circuit, multiple switch, “gatekeeper switch-on isolation switch GHK, first connected Ten 15V DC power supply, vacuum circuit, reset circuit and other components, it is the core of the entire system, under the command of Cheng Yue order to complete a variety of signal detection, analysis and processing and output results.

The phase-to-phase lockout detection circuit principle is used to determine the integrity of the circuit. According to the test results available through the detection principle, the phase failure can be detected very easily; the detection results A, B, C three-phase line conditions l, 2 output signal conditions A, B, C three phases are not Phase-breaking is close to 5V voltage output A-phase has phase-off all close to 0v voltage output B-phase has a phase-off 1 output 0v, 2 output 5VC phase has a phase-breaking l output 5V, 2 output 0V1.

The detection circuit of the leakage lockout detection circuit of the leakage lockout detection circuit is as shown in the figure. Using the power supply as a direct-strength-flow detection power supply, the insulation resistance to the ground in the power grid is equal to and between them, and then it is connected with melons and civilians. When the grid is normal, that is, in the 66OV grid 15V start initialization starts the watchdog timer start software timer fault class judgment subroutine display subroutine ABC2 software design Because the detection of the protection system is more, so the software design uses a modular structure , Cyclic scan mode. It has the advantages of clear structure, flexible combination and convenient debugging.

All programs consist of main program module and phase sensitive protection subroutine module, overvoltage and undervoltage judging subroutine modules, short circuit, leakage current, latching subroutine module, negative sequence protection subroutine module and overload protection subroutine module, etc. The main program block diagram becomes. The main program block diagram is shown in 5.

Interrupt service procedures A/D leakage lock detection circuit principle Insulation resistance value should be greater than 2 soil 1kn, 380v insulation resistance value in the grid should be greater than 7 persons Ikn, the output between the field output low potential. Once the insulation resistance of the grid to the ground drops below the specified value, the output is high potential, in order to detect leakage and achieve blocking transmission.

The circuit principle of the short-circuit lockout detection circuit short-circuit lockout detection is as shown. Components such as the composition of three-point inductance oscillator, oscillation frequency of 25kHz, high-frequency detection signal by L,, L4, QS-CR connected to the three-phase power grid. When there is no short circuit in the power grid, the phase-to-phase impedance of the power grid is relatively high. The block diagram of the interrupt service routine is shown in Figure 6. The program interrupts the program for the microcontroller as a timed interrupt mode, the program performs a self-test on the state of the various parts of the microcontroller, and determines whether the software execution is correct, and corrects the process errors caused by the sudden interference to ensure the reliability of the SCM operation.

At present, the majority of mines' main fan operation monitoring methods are generally adopting a patrol inspection method. The related parameters of the operation are regularly checked and recorded. There are many deficiencies in this backward way. Without monitoring the system, the temperature can be directly converted into serial digital signal processing, and each Dsl82o has its own unique product serialization in its ROM, enabling the multi-point temperature measurement and control system to Single can timely and accurately monitor the whole process of the fan's operating parameters, and the vibration records cause the data cluster to be unrealistic.
