Detail Siemens Reyrolle 7XG22 – 2RMLG

The range of 2RMLG Test Blocks, housed within an Epsilon enclosure, offers facilities for monitoring and secondary injection testing of power system protection schemes in conjunction with the 2RMLB-S multi-fingered test plug. The 2RMLG Test Block has 14 pairs of spring loaded contacts which are linked to a terminal block positioned at the rear of the enclosure. The 2RMLG07 is coded to only accept the 2RMLB-S7 Test Plug which has connection terminals 21, 23, 25 & 27, internally – For typical application see Fig 4. The 2RMLG08 is coded to only accept the 2RMLB-S8 Test Plug which has internal pairs 1& 3, 5& 7, 9& 11 and 15& 17 shorted together internally – For typical applications see Figs 5, 6, 7 & 8. The 2RMLG09 is coded to only accept the 2RMLB-S9 Test Plug which has internal pairs 1-3-5-7, and 17-19 shorted together internally. Each pair of contacts is normally closed completing the circuit through the test block when the associated protection equipment is in use. For testing purposes the test block can be accessed by removing the front cover. The 2RMLG 01 has a metallic probe attached to the front cover assembly which when withdrawn open circuits the 2 contacts at position 13 and 14. The main dc auxiliary supply to the protection scheme or relay can be wired to this circuit to prevent inadvertent tripping of the protection circuit after removal of the cover and during the test procedure. The 2RMLG 02/ 07/ 08/ 09 do not include the above facility and contacts 13 and 14 are normally closed. These contacts must not be used for current circuits, as the relevant contact finger on the 2RMLB test plug is shorter in this position. The short test finger in position 13-14 on the 2RMLB will open contacts 13-14 in the test block after the other fingers have made contact in all other positions. Description Fig 1 & 2. Note: It is important that the sockets in the test plug ( 2RMLBS-1) which correspond to the current transformer secondary windings are linked prior to the test plug being inserted into the test block. This will ensure that the current transformer secondary windings are short circuited prior to disconnection from the protection scheme or relay ( as shown in Figure 3) . If the dc auxiliary supply is to be used during testing it can be linked using the sockets in the test plug. Operation of the contacts can be monitored by connecting the test equipment to the protection scheme or relay with the even numbered sockets of the test plug. If a number of 2RMLG test blocks are connected to a relay it is recommended that the dc supply be routed through each of them to safeguard against inadvertent operation. Siemens Protection
