Fatti chiave dell'applicazione

Settore


Garantire la sicurezza elettrica con le celle di prova dell'impianto

Applicazione


Conferma affidabile che l'alta tensione non è più presente

Parametro misurato


Uscita basata su interruttore al raggiungimento di una soglia di tensione definita dall'utente

Requisiti principali


Garantire la sicurezza sul lavoro in un ambiente ad alta tensione

Rilevamento accurato di una soglia di tensione non sicura

Conferma del funzionamento del sistema

Sicurezza attraverso il rilevamento della presenza di tensione

Descrizione dell'applicazione

Le celle devono essere fissate in conformità alla norma EN 50191 (o a norme e regolamenti di sicurezza simili, in base al paese di installazione).

Requisiti dell'applicazione

Poiché il processo di qualificazione dei componenti prevede tipicamente test ad alta tensione, un prerequisito importante per stabilire la sicurezza del personale che può rientrare nelle celle di prova è la conferma affidabile che l'alta tensione non è più presente.

Perché Knick?
Il Knick P52000VPD è un robusto sensore che fornisce un'uscita basata su un interruttore a stato solido una volta raggiunta una soglia di tensione definita dall'utente. Il rilevamento della presenza di tensione può essere effettuato fino a +/- 4200 V CA/CC, con isolamento continuo a un livello ancora più elevato, pari a 4800 V CA/CC. Un'uscita relè diagnostica disponibile conferma l'indicazione dello stato di "power good". L'alloggiamento del dispositivo con copertura in fibra di carbonio indurita garantisce la protezione delle dita con i terminali di ingresso ad alta tensione.

Test systems generate control voltages in a battery model in order to simulate temperature conditions for battery management systems (BMS) and evaluate the temperature management of the BMS.
With the help of hardware in the loop (HIL) tests, prototypes of devices like the traction inverters, for example, can be evaluated in various battery, load, and error situations without having to test the converter itself on test benches or in vehicles.
The production process of HV heaters involves many steps, with some of them being manual. Various tests are carried out in-line, according to the corresponding manufacturing stages.
For battery electric commercial vehicles, there is a quick-charging option via pantographs. This requires a contact between an external infrastructure system (with movable pantographs) and permanently installed charging rods on the vehicle roof. A DC roof container contains components that check the charging connection and the corresponding voltage, and establish the connection to the other on-board systems.
During battery tests, the charging and discharging operations (battery cycles) are continuously simulated in a HIL (hardware in the loop) configuration that corresponds to the typical use profiles when the electric vehicle is in operation. In the process, a series of parameters are measured, including capacity, battery efficiency, and self-discharging.
