TECHNICAL FIELD
[0001] The utility model relates to circuit breaker technical field especially one button sequential control double confirmation porcelain post circuit breaker. BACKGROUND
[0002] Circuit breaker refers to the switch device that can close, carry and open the current under normal loop condition and can close, carry and open the current under abnormal loop condition within the stipulated time. Porcelain post circuit breaker is one of the commonly used circuit breakers, and the breaking point of the porcelain post circuit breaker is supported at the top end by a porcelain post, which serves as insulation and support. This circuit breaker is cheaper than the tank type circuit breaker, so it is widely used. The porcelain post circuit breaker is used in high-voltage power grid, and its structure is composed of inlet and outlet line caps, inlet and outlet line porcelain sleeves, current transformers, transformer connection sheaths, arc extinguishing devices, chassis, transmission boxes, transmission connecting rods, opening springs and operating mechanisms, adopts pressure gas type arc extinguishing principle, and has a complex structure, and is mostly made of cast aluminum alloy,
[0003] With the rapid development of power grid engineering, the reliability requirement of equipment operation is higher and higher, and the one-key sequential control double confirmation technology of the transformer substation has been further developed. The circuit breaker itself can send a split and combination position signal, and a remote signal is needed in the double confirmation to improve the double confirmation function. Usually, a probe is added and a live display host is connected to complete the confirmation of the signal. At present, most of the probes in the power grid industry are hung on the base of the porcelain post circuit breaker. However, since the probe is an independent part, the probe protrudingly arranged is easy to be damaged in the transportation process. UTILITY MODEL CONTENTS

[0006] As a further improvement of the utility model, the bottom of the support frame is provided with a foundation bolt.
[0007] As a further improvement of the utility model, the foundation bolt is fixed by a long screw.
[0008] As a further improvement of the utility model, the single-pole circuit breaker is double-section and is connected through a wiring board.
[0009] As a further improvement of the utility model, the support frame and the base are provided with an angle iron at the connecting position.
[0010] As a further improvement of the utility model, the single-pole circuit breaker is filled with SF6 gas.
[0011] Compared with the prior art, the utility model has the beneficial effects that in the scheme, the probe is installed on the base, the L-shaped bent plate is fixed to the base, the fixing plate is fixed to the L-shaped bent plate, during delivery, the fixing plate is installed parallel to the base, after arriving at the substation site, the fixing plate is adjusted to be installed perpendicular to the base, the probe can rotate by 180 DEG, and safe transportation is ensured.
