Problems solved by technology

[0002] Plum blossom contacts are used in high-voltage vacuum circuit breakers. When the pressure of the Plum Blossom contacts decreases, the contact resistance will increase. Larger currents will cause the Plum Blossom contacts to heat up severely, resulting in oxidation and heating failures; when the Plum Blossom contacts If the pressure is too high, when the circuit breaker is pulled out and inserted into the cabinet, the plum blossom contact will be severely worn, the contact resistance will increase, and the severe heat will cause the main circuit of the high voltage vacuum circuit breaker to fail. Therefore, a detection plum blossom contact is required. pressure detector

Embodiment Construction

[0026] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.

[0027] It should be noted that all directional indications (such as up, down, left, right, front, back...) in the embodiments of the present invention are only used to explain the relationship between the components in a certain posture (as shown in the accompanying drawings). Relative positional relationship, movement conditions, etc., if the specific posture changes, the directional indication will also change accordingly.

Abstract

The invention discloses a pressure detector. The pressure detector comprises a host and a probe. One end of the probe is connected to the host, and the other end of the probe is provided with a pressure sensor. The probe is further provided with a limiting member adjacent to the pressure sensor. When the probe is inserted into the tulip contact, the limiting member abuts against at least one of the spiral spring, so that the pressure sensor abuts against the spiral spring in the tulip contact. The invention provides a pressure detector for quickly detecting the pressure of a tulip contact.

Description

technical field [0001] The invention relates to the technical field of detection equipment, in particular to a pressure detector. Background technique [0002] Plum blossom contacts are used in high-voltage vacuum circuit breakers. When the pressure of the Plum Blossom contacts decreases, the contact resistance will increase. Larger currents will cause the Plum Blossom contacts to heat up severely, resulting in oxidation and heating failures; when the Plum Blossom contacts If the pressure is too high, when the circuit breaker is pulled out and inserted into the cabinet, the plum blossom contact will be severely worn, the contact resistance will increase, and the severe heat will cause the main circuit of the high voltage vacuum circuit breaker to fail. Therefore, a detection plum blossom contact is required. pressure detector. Contents of the invention [0003] The main purpose of the present invention is to provide a pressure detector, aiming to provide a pressure detect...
