What is an SHV?
The SHV (safe high voltage) connector is a type of RF connector used for terminating a coaxial cable. The connector uses a bayonet mount similar to those of the BNC and MHV connectors, but is easily distinguished due to its very thick and protruding insulator.
What is a hv plug?
High voltage connectors (HV connectors) are typically used in AC, DC and RF applications that experience high voltage. These connectors make it possible to transmit signals with high voltage ratings without posing safety risks to operators. Any connector above 1 kVDC is considered high voltage.
What is HVIL loop?
HVIL, or high-voltage interlock loop, is a safety feature of hybrid and all-electric vehicles that protects people during the assembly, repair, maintenance and operation of a vehicle. HVIL also helps protect a vehicle’s driver and passengers in the event of an accident.
What happens if the HVIL 12 volt circuit is interrupted?
When HVIL circuit fails shorted high, low or open, a Diagnostic Trouble Code (DTC) is set and the Service Soon Lamp is illuminated to indicate to a service technician that additional safety precautions need to be taken when servicing the HV system.
Is HVIL a high-voltage circuit?
In electric vehicles, HVIL consists of one or more low voltage loops in series and control module. A high-voltage interlock loop in the high-voltage electrical circuit to prevent any danger caused by improper disconnection of the high voltage connector on an active high-voltage system.
What is the purpose of the HVIL?
The HVIL system is designed to protect anyone who might come into contact with high-voltage components of an electric vehicle at any stage in its lifecycle. HVIL is not necessary in gas-powered vehicles because their electrical systems operate at low voltages and pose no risk to operators and service technicians.
What happens when the HVIL is interrupted?
What is an HVIL circuit?
High voltage interlock loop is a safety circuit specially designed to monitor the integrity of high voltage circuits. It is a current and voltage loop mechanism. In electric vehicles, HVIL consists of one or more low voltage loops in series and control module.
What are the two types of interlock loop designs?
There are two main types of interlocks: safe and non-safe. Some systems require safe and non-safe interlocks to create a control system.
What is the purpose of the high-voltage interlock circuit?
Interlock is a current and voltage loop mechanism used to detect tampering or opening of the high-voltage equipment or service disconnect switch.
What are the recommended items that should be used when working with the high-voltage HV circuits of a hybrid electric vehicle?
Class 0 insulated rubber gloves, or lineman’s gloves, are required whenever working near high-voltage parts on an electric or hybrid electric vehicle.
What safety equipment do you need to work on a hybrid car?
You should wear appropriate PPE (aprons, boots, gloves, etc.) with specs meeting the voltage range and rating you’re handling, and never use expired gear unless it has been recertified, McGinn said. For rubber gloves, you’re likely seeking a pair rated for Class 0 — not 00 or 1 — McGinn said.
