Description
Technical field
The utility model relates to a kind of isolating switch electrical equipment, specifically contact supporter structure in a kind of isolating switch electric equipment products.Belong to the manufacture of low-voltage electrical series products and applied technical field, mainly apply I and II load, building, metallurgy, coal, oil, chemical industry, industrial medical treatment and industrial and mining enterprises etc.
Background technology
Isolating switch electric equipment products, the advantages such as simple in structure, novel, good looking appearance and Operation and Maintenance facility, the characteristic of utilizing shell self to have, make switch have very high dielectric property, protective capacities and reliable processing safety, operating mechanism is spring energy-storage, the acceleration mechanism of instantaneous relase, makes the divide-shut brake speed of switch faster, adopts momentary connection and disjunction double break contact structure simultaneously.Switch connects and disjunction double break contact structure by operating mechanism, has realized the function of connection and the disjunction of device for switching.
Though the contact supporter system of isolating switch product is verified for many years through product at present, performance is up to standard, but still has very large room for promotion.Traditional contact supporter system is made up of four kinds of parts of sheet and spring leaf under contact supporter, quick-break blade upper slice, quick-break blade.It carries out in the process of divide-shut brake at switch is the process of carrying out a grafting with contact chip, in the coordinating of contact supporter and quick-break blade, in the middle of two quick-break blades, there is a lattice gear, because there is certain deviation in machining accuracy, so just can not make the center of upper and lower two quick-break blades remain on same center line with the center of the contact chip that will peg graft, can make like this switch under the state of work, likely occur the phenomenon of switch contact melting welding.Supporter structure is in the time carrying out divide-shut brake, and the state of upper and lower two quick-break blades will be from the parastate not contacting with contact chip to rigidly connecting the state that upwarps while touching with contact chip, then to the parastate after contacting with contact chip completely.The ability that too much can affect switch connection and disjunction of switch "on" position and the speed of switch divide-shut brake in the time closing a floodgate.
Summary of the invention:
The purpose of this utility model is the overall performance for improving switch, mainly solves existing contact supporter structure in the time closing a floodgate, due to the technical problem of the ability that too much can affect switch connection and disjunction of switch "on" position and the speed of switch divide-shut brake.
The purpose of this utility model is achieved through the following technical solutions: isolating switch electrical equipment contact supporter mechanism, comprises on contact supporter (3), contact chip (2), quick-break blade (7) and strutting piece (4) under (6), quick-break blade.Said structure part is arranged in switch base (1).Above-mentioned contact chip (2) is fixedly connected with switch base (1), makes contact chip (2) keep inactive state in the position of specifying.On quick-break blade, (6) are connected by the mode of pegging graft with strutting piece (4), under same quick-break blade, (7) are connected by the mode of pegging graft with strutting piece (4), (7) under (6) and quick-break blade on the quick-break blade of two grafting strutting pieces (4) are placed with a side opposing parallel of cambered surface, and be fixed on contact supporter (3) by spring leaf (5), because it is by being flexible coupling, therefore on quick-break blade, under (6) and quick-break blade, (7) can carry out upper and lower movement on contact supporter (3), the contact supporter assembling is called to contact supporter mechanism, the contact supporter mechanism that assembling is completed is connected with switch base (1), by the horizontal slide in switch base (1), contact supporter mechanism can be moved on the slideway in switch base (1).While movement on the slideway of contact supporter mechanism in switch base (1) and contact chip (2) peg graft, make (6) on quick-break blade occur to contact with (7) under quick-break blade and contact chip (2), so just make switch carry out connection and disjunction.
Above-mentioned contact supporter mechanism is mainly used in 100 to 630A tri-utmost points and 100 to 630A tetra-utmost point isolating switch electrical equipment.
The beneficial effects of the utility model and advantage:
Contact supporter mechanism makes the front end of upper and lower two quick-break blades form the tip-tilted elevation angle, make like this switch be positioned at the state upwarping before contact chip contact to the parastate contacting completely with contact chip at the state of the speed per hour breaking sheet that closes a floodgate, when combined floodgate, only need to, through two states, just make switch and lock.Traditional product needs just can make switch and lock through three states, and the utility model effectively raises connection and the breaking capacity of switch like this, has also improved the speed of switch divide-shut brake simultaneously.The advantage of contact supporter is to make upper and lower two quick-break blades on upper and lower both direction, carry out moving up and down of coverage, solve the Welding Phenomena that does not cause switch contact because of the center of contact chip and the center of upper and lower two quick-break blades on same center line, make the contact of switch there is good connection simultaneously, the design of strutting piece makes the face upward state of upper and lower two quick-break blades from the parastate of traditional structure to new construction, has improved the overall performance of switch.
