Definitions

  • Test device for a control cabinet with an input terminal block
  • the invention relates to a test device for a control cabinet comprising a cabinet mounted on the input terminal block with several individual terminals.
  • the devices used for monitoring and controlling electrical equipment in switchgear and / or power plants are checked during commissioning and also during any required maintenance on their functioning.
  • these devices can be protective devices that are housed in a control cabinet.
  • test switches or test blocks are used by means of which a test device can be connected to the devices arranged and to be checked in the control cabinet. These test switches or test blocks are connected by means of a separate wiring to the circuits inside the cabinet. The test switches or test blocks as well as their connection wiring are an additional expense. In addition, the inspection of the internal circuits and equipment is only performed from the points at which the test switches or the test blocks are connected.
  • Each individual terminal of the input terminal block of the test device contains a) an input terminal contact for connecting a device or electrical connection conductor arranged outside the cabinet, b) a cabinet connection contact for connecting one inside the cabinet c) a first terminal test contact connected to the input terminal contact, d) a second terminal test contact connected to the cabinet terminal contact, and e) a circuit breaker arranged between the input terminal contact and the first terminal test contact on the one hand and the cabinet terminal contact and the second terminal test contact on the other hand.

This will cause a false trip of the circuit-breaker is safely prevented if the control cabinet: is connected to a test device for checking by means of the test plug.
  • test plug is designed so that when plugging the test plug on the input terminal block after opening the circuit breaker of the circuit breaker terminal, the first terminal test contacts the current transformer terminals are shorted , This prevents unwanted damage to the CT due to disconnection of the circuit connected to the CT.
  • test plug is also designed so that when plugging the test plug on the input terminal block after opening the circuit breaker of the circuit breaker terminal and after shorting the first terminal test contacts the current transformer terminals all disconnected disconnectors are opened. This switching sequence prevents unwanted influences on the equipment externally connected to the control cabinet and allows a safe transition to the test mode.
  • the input terminal block is arranged on a front side of the control cabinet.
