How Does The Withstand Voltage Tester Measure
Operation Block Diagram:
The Program-Controlled Leakage Current Tester Withstand Voltage Checker Is Composed Of A High-Voltage Boost Circuit, A Leakage Current Detection Circuit, And An Indicating Surface. The High-Voltage Boost Circuit Can Adjust The Output Required Test Voltage, And The Leakage Current Detection Circuit Can Set The Breakdown (Protection) Current , Instruct The Surface To Directly Read The Experimental Voltage Value And Leakage Current Value (Or Set The Breakdown Current Value). When The Sample Reaches The Required Time Under The Required Experimental Voltage, The Instrument Will Automatically Or Be Forced To Block The Test Voltage; Once A Breakdown Occurs, The Leakage Current Exceeds The Set Breakdown (Protection) Current, The Output Voltage Can Be Automatically Blocked, And An Alarm Will Be Issued At The Same Time , In Order To Confirm Whether The Sample Can Accept The Regular Dielectric Strength Test.
The Withstand Voltage Tester Is The Basic Instrument For Measuring Withstand Voltage Strength. It Can Intuitively, Accurately, Quickly And Reliably Inspect The Breakdown Voltage, Leakage Current And Other Electrical Safety Functional Indicators Of Various Tested Objects, And Can Be Used As AC (Direct) The High-Voltage Source Is Used To Check The Components And Functions Of The Whole Machine. The Withstand Voltage Inspection Product Series Are Planned In Accordance With International And Domestic Safety Regulations Such As IEC, ISO, BS, UL, JIS, Etc. The Withstand Voltage Ranges From 3kV To 10kV, And The Leakage Current Ranges From 0 To 200mA. Special Requirements Are Determined Separately. Suitable For Various Household Appliances, Power Supplies, Cables, Transformers, Terminal Blocks, High-Voltage Bakelite Appliances, Switching Power Supply Plug Sockets, Motors, Electronic Instruments, Surfaces, Complete Machines, Etc., As Well As The Inspection Of The Safe Withstand Voltage And Leakage Current Of The Strong Current System, It Is Also An Indispensable Pressure Test Equipment For Laboratories And Technical Departments.
The Pressure Tester Series Products Are Based On The Absorption And Digestion Of Foreign Pressure Testers, Combined With The Practical Application Of Many Chinese Users To Advance And Improve. The Withstand Voltage Tester Is A Series Of Fully Digital Display Withstand Voltage Testers. The Inspection Voltage, Leakage Current, And Inspection Time Are All Digital Flashing. The Leakage Current Can Be Set Arbitrarily According To Different Safety Regulations And Different Needs Of Users. There Is A Countdown Digital Flashing At The Measurement Time, Which Makes The Accuracy Of The Inspection Time Advance To More Than ±1%, And The Inspection Plan Advances To 99s, The Function Is More Abundant And Useful, And It Is At A Better Level In Terms Of Technical Functions And Quality Reliability.
Features And Different Uses Of Vibrometer
The Vibrometer Is Also Called The Vibration Analyzer Or The Vibrometer Pen. The Principle Of The Vibrometer Is Designed By Using The Piezoelectric Effect Of Quartz Crystal And Artificially Polarized Ceramics. Generally Choose Piezoelectric Structure To Work.
The Program-Controlled Leakage Current Tester Is Designed With Artificially Polarized Ceramic Piezoelectric Effect. It Has The Function Of Determining The Intensity (Speed) In The Oscillation Table, And Also Has The Function Of Specifically Determining The Defects Of Bearings And Gearboxes, And Has Clear Diagnostic Specifications. , Used For Periodic Motion Measurement To Detect Imbalance And Violation Of Motion Machinery. The Vibrometer Uses A High-Function Accelerometer To Complete Accurate And Repeatable Measurements. The Vibration Meter Is Suitable For The Measurement Of The Conventional Oscillation Of Mechanical Equipment, And Can Measure The Oscillation Displacement, Velocity And Acceleration. It Is Widely Used In Machinery Manufacturing, Electric Metallurgy, Vehicles, General Aerospace And Other Fields.
The Vibration Meter Is Equipped In The Equipment Management Organization. According To The Nature Of The Work And The Division Of Labor, Different Vibration Meters Are Provided. The Ministry Of Energy Is Equipped With The Analysis System Of The Japanese Rion, And Has A Data Collection Defect Diagnosis System. The Measurement Parameter Is Acceleration. , Speed, Displacement, Temperature, Rotation Speed. For Branch Inspectors, A Multi-Function Portable Oscillator Is Equipped With Measurement Parameters Such As Acceleration, Speed, Displacement, Etc., Which Are Convenient For Inspectors To Carry, And Are Mainly Used For Random Inspection Of Equipment Operation. Inspection And Repair Personnel Who Grasp The Basic Parameters Can Be Equipped With A Portable Series Of Vibration Meters, Which Are Suitable For Testing The Acceleration, Speed, And Displacement Of All Mechanical Equipment Such As Motors, Pumps, Fans, And Compressors.
Vibration Meter Measuring Method And Judgment Basis
1. Selection Of Measuring Points Of The Vibration Meter: Use The Vibration Meter To Check The Bearings And Axial End Points Of The Primary Equipment, And Be Equipped With An On-Site Test Record Table. Each Measuring Point Must Correspond To Each Other.
2. Measuring Cycle Of The Vibrometer: It Needs To Be Tested Every Two Weeks Just After The Equipment Is Overhauled Or Close To The Overhaul; It Is Tested Once A Month During Normal Operation; If There Is A Significant Change Between The Measured Value And The Last Measured Value, The Inspection Should Be Strengthened Density, In Order To Prevent Unexpected Accidents And Constitute Defective Shutdowns.
3. The Basis For Determining The Measured Value Of The Vibrometer: Refer To The International Standard ISO2372.
Rotation Speed: 600～1200r/Min, Oscillation Measurement Plan: 10～1000Hz.
Normally, When The Equipment Is In Normal Operation, Its Detection Speed Value Is 4.5~11.2mm/S (Units Above 75kW) Is Planned For Monitoring And Application. If It Exceeds 7.1mm/S, It Is Necessary To Consider Organizing Major Repairs. To Confirm This Value, In Addition To Considering The Capacity Of The Equipment Motor, It Must Also Consider The Aspects Of Strong Continuity Of Operations, Safety, Reliability And High-End.
