Perguntas frequentes

Somos fabricantes de equipamentos de teste profissionais que possuem nossa própria equipe de P&D, oficina de produção, sistema de controle de qualidade e departamento de marketing.

Oferecemos garantia de 12 meses e manutenção vitalícia. A garantia aplica-se ao comprador original, ou seja, o equipamento não apresentará quaisquer defeitos de materiais ou fabricação durante um período de um ano a partir da data da compra. A garantia cobre apenas defeitos decorrentes do uso normal e do serviço regular, excluindo quaisquer avarias e danos resultantes de uso abusivo, alteração, instalação inadequada, negligência ou condições ambientais adversas, não sendo devidos a problemas de qualidade.

Normalmente, o prazo de entrega é de cerca de 15 dias úteis após o pagamento. Para alguns produtos personalizados especiais, o prazo de entrega será de 15 a 30 dias úteis, dependendo do parâmetro técnico exigido pelo cliente.

Testador de interruptores de circuito KVCB-12Y

Circuit Breaker Tester is a specialized instrument designed to meet the requirements for testing the action characteristics of various high-voltage switches. It can accurately measure the mechanical dynamic characteristic parameters of high-voltage circuit breakers across different voltage levels, including low-oil, high-oil, vacuum, and sulfur hexafluoride types. For circuit breakers with closing resistance, it can precisely measure the closing resistance and switching waveforms.

Características

Unique Advantage

  • Timing:All 12 common breakers have synchronized opening and closing times, with similar phase characteristics.
  • Reclosing:Each breaker’s closing-opening and opening-closing cycles are measured, including one opening time, one closing time, two opening times, short-circuit duration, and current interruption values.
  • Bounce:This includes the closing bounce time, number of bounces, bounce process details, and bounce waveform for each breaker, as well as the rebound amplitude during opening.
  • Speed:This covers the opening and closing speeds, maximum speed, and the time-travel characteristic curve.
  • Current:This includes the opening and closing current values and the current waveforms for the opening and closing coils.
  • Action Voltage:The machine provides a digital adjustable power supply (DC 30-250V/20A) for testing. It automatically performs low-voltage action tests and measures the action voltage values for each breaker.
