Touch board suitable for handcart-type switch cabinet

Abstract

The invention discloses a touch board suitable for a handcart-type switch cabinet. The touch board comprises a plurality of contacts arranged on a transverse board, wherein each of the contacts comprises a dynamic contact and a static contact that are matched with each other; a guide groove is arranged on the side wall of each of the static contacts; the tail end of each of the contacts is fixed with the transverse board; each of the dynamic contacts is connected with an outer ring of each of the static contacts by a screw matched with each of the guide grooves in a sleeving manner; the outer ring of each of the static contacts is sleeved with a spring. Through an improvement on a contact structure of the contacts, the toughness of the contacts is enhanced, and the cooperation degree of operation is improved, so that an accident of deformation of the dynamic contacts caused by a switch cabinet valve mechanism can be prevented; through adoption of a hollow structure in the contacts, the cooperation condition of the dynamic contacts and the static contacts can be observed conveniently, the abnormal condition is timely discovered conveniently, and maintenance personnel can make a timely adjustment conveniently. Due to the fixed height and polar distance of the contacts, the touch board is suitable for most of polar distances of switches and has wide applicability, the maintenance quality is improved, the maintenance cost can be greatly lowered, the interruption duration of equipment can be greatly shortened, and the existing maintenance process is effectively perfected and complemented, therefore, the touch board has strong practicability.

Description

technical field [0001] The invention relates to a touch panel, in particular to a touch panel suitable for a handcart type switch cabinet. Background technique [0002] At present, the 10kV central switchgear has been widely used in the power system due to its own advantages, but there are still some deficiencies in the actual operation process. [0003] First of all, the full sealing of the switchgear makes it impossible to directly see the process of pushing the internal switch from the "test" position to the "operating" position, and this process is precisely the key process related to whether the switch can operate normally. , or the abnormal position of the contact will cause the switch contact to cause a heating fault due to poor contact (and this fault cannot be detected by conventional means such as infrared temperature measurement due to the airtightness of the central cabinet during operation), and it will be more serious if it is serious. It will cause deformatio...
