In the field 35KV voltage change test, it is often necessary to push the voltage changer to the maintenance position, and remove the secondary small line to perform the secondary DC resistance, polarity test, insulation and excitation DC withstand voltage test of the voltage changer. However, for the 10KV GIS (Gas Insulated Switchgear) cabinet, the voltage transformer cannot be pushed to the test position for test work, and the verification work of relay protection needs to be accessed from behind the watt-hour meter screen. This increases a lot of workload, and more equipment is involved, and the possibility of damage to the equipment is greater. In addition, the secondary small wire needs to be frequently disassembled and assembled during the test, which often has a certain breakage rate. It will have a certain impact on the normal operation of the equipment in the future.

Considering the reliability and safety, how to safely take power from the secondary terminal block is also an urgent problem to be solved.

Detailed ways

A preferred embodiment of the present invention will be specifically described below with reference to FIGS. 1 to 6 .

As shown in Figure 1 and Figure 2, the present invention provides a fast connection device for safe power taking, including:

A connection row 101, which is arranged on the secondary terminal row 11, and the connection row 101 has grooves 1011 and several through holes 1012;

A fixing component, which passes through the groove 1011 on the connecting row 101, and fixes the connecting row 101 on the secondary terminal row 11;

The power-taking component passes through the through hole 1012 on the connection bar 101 and contacts with the socket on the secondary terminal bar 11 .

As shown in FIG. 4 , the fixing assembly includes a tensioning sleeve 103 and a jacking screw 104 disposed in the tensioning sleeve 103 .

As shown in FIG. 4 and FIG. 5 , the tensioning sleeve 103 includes: a fixed locking key 1031 disposed at the head and an opening portion 1032 disposed at the tail, and the opening portion 1032 has a chamfered structure 1033 .

As shown in Figure 4, the fixed locking key 1031 on the tensioning sleeve 103 is embedded in the groove 1011 on the connecting row 101, which limits the rotation of the tensioning sleeve 103, and the jacking screw 104 presses the chamfered structure downward along the direction A 1033 , forcing the opening 1032 of the tensioning sleeve 103 to expand to both sides along the direction B, so as to quickly install and fix the connecting row 101 and the secondary terminal row 11 .

As shown in Figure 6, the power-taking component includes:

Conductive copper needle 107, which is arranged in the through hole 1012 on the connecting row 101, and the lower end contacts the jack on the secondary terminal row 11;

The spring 106 is arranged in the through hole 1012 on the connecting row 101 and is located on the conductive copper pin 107;

The conversion sleeve 105 is arranged in the through hole 1012 on the connecting row 101 and is located on the spring 106 for inserting the test plug 22 .

The size of the conductive copper pin 107 matches the size of the socket on the secondary terminal block 11, the size of the conversion sleeve 105 matches the size of the pin test wire, and the conversion sleeve 105 is connected to the pin test wire. The wire, the conversion sleeve 105 and the conductive copper pin 107 realize the size conversion between the socket on the secondary terminal block 11 and the pin test wire. The conversion sleeve 105 is made of epoxy resin plate to ensure a good Insulation, while the spring 106 located between the conversion sleeve 105 and the conductive copper needle 107 provides a reliable downward force, ensuring the connection capability and conductivity of the entire power-taking assembly.
