3.7 Electrical safety

SYIL 7 Series machines contain a range of electrical components that must be properly configured and monitored to ensure a safe working environment.

This section provides important electrical safety considerations and instructions for preventing potential electrical hazards.

3.7.1 Electrical hazards and prevention measures

The human body is highly prone to harm from electricity, and the risk of injury or death increases with voltage levels. While people have suffered fatal accidents from as little as 35 volts, many mistakenly believe they can withstand contact with 100 volts or more.

Though the human body has strong capacity for resisting electrical currents, even low current levels can have a significant impact. The following chart compares different current levels and their impact on the human body:

Current Levels and Impacts
Current Impact on the Human Body Current Impact on the Human Body
Less than 1mA Feeling of weakness and tingling Higher than 50mA Pain and physical injury
Less than 5mA Painful shock Higher than 100mA Fatal injury
10~20mA Pain accompanied by uncontrollable muscular spasms    

3.7.2 Overcurrent relays

When the voltage in an electrical circuit exceeds its rated value, overcurrent relays can limit the current and protect the circuit, making their installation in the machine’s electrical system essential.

Overcurrent relays can be categorized as electric relays, thermal inductance relays, and magnetic inductance relays. Among these types, thermal inductance relays are used most widely.

Thermal inductance overcurrent relays are manufactured with dual-layer metal plates. When the current exceeds the circuit’s rated value, the dual-layer metal board will receive an electrical signal to shut down the current due to overheating.

Thermal inductance overcurrent relays come in several varieties, as shown in the following comparison chart:

Overcurrent Relays
Type Description
Direct heating Directly conducts the current to the dual-layer metal board, with a high sensitivity to movements; however, its resistance level results in some loss of current.
Semi-indirect Features a dual-layer metal board with asbestos insulation and thermal component coils; one side of the thermal component connects to the dual-layer metal board, enabling it to conduct the current.
Thermal release Thermal release Does not transmit current signals to the dual-layer metal board; instead transmits signals to thermal components to generate activation gradually.

3.7.3 Switch control faults and possible diagnosis

This section identifies commonly occurring switch control problems and their causes.

 

Inactive controls and switch functions

Possible causes of inactive controls or switch functions include:

  • Electrodeposition resulting from short circuit

  • Low switching volume

  • Vibration of electric contacts due to low voltage (resulting in electro-deposition)

  • Part of the magnetic core is too long, or the part entering the oscillator is too short
  • Sticky oil on the magnetic core

Abnormal current attenuation on electric contacts

Possible causes of for current abnormalities on electric contacts include:

  • Electric arcs generated by short circuits, low switching volume, excess motor worktime, negative phase damping, or increased remanence induction.

  • Excessive operation
  • Electric arcs generated by worn or dirty contacts

To resolve these problems, separate the affected electric contacts and take the following measures:

  • Adjust the electric contacts so their surfaces are parallel when connected.

  • Remove any foreign matter adhering to the contact points.

Thermal induction overvoltage relay faults

Possible causes of faults in thermal induction overvoltage relays include:

  • Heater burnout

  • Operation performance fault

Possible causes of phase position short circuits include:

  • Dust or humidity in the phase position

  • Overheating of the phase position

Electrical coil fires

Possible causes of fire on the electrical coils include:

  • Short circuits

  • Voltage levels exceeding 110% of the rated voltage
  • Voltage levels below 85% of the rated voltage

  • Deterioration due to exposure to cutting liquid

  • Faults due to contact separation
  • Overuse of switches

Electromagnetic vibration

Possible causes of electromagnetic vibration include:

  • Low voltage levels

  • Foreign matter adhering to electric contacts
  • Rusted electrodes

  • Absent shielding coil

3.7.4 Precautions for working with electrical equipment

Please these precautions to minimize the risk of harm or damage.

Explosion-proofing

  • Due to the presence of explosive hazards including gas, dust, and other flammable materials, operators should avoid creating sparks while operating the machine. To counter the risk of explosions, switches and other devices should be installed in explosion-proof housing structures with the appropriate pressure, liquid chemical, or other explosion-type resistance ratings.

Electrical equipment inspections

  • Regular safety inspections are needed for all insulated wires and covers, conductive wiring and cables, and protective switch casings. Ensure that electrical equipment safety inspections are arranged in accordance with worksite electrical specifications.

  • Inspect the equipment to ensure it is properly grounded and check for breaks in the conductive wiring.
  • Inspections of the fuse box and related electrical safety systems must be conducted at regular intervals, regardless of their performance.

Preventing hazardous static electricity

  • In areas where gas, dust, and other flammable or explosive materials are present, the sudden discharge of static electricity can result in explosions.

  • Conveying gasoline and other liquids, cutting solid materials, and performing printing operations can present an elevated risk of static discharge.
  • In order to limit the generation of static electricity, measures should be taken to reduce friction, maintain a steady flow rate, and ensure the proper grounding of all equipment.

  • If necessary, use an inhibitor or air ionization mechanism to reduce static electricity at the worksite.
