Background technique
Existing earthing switch generally all includes shell, connection terminal module, electric control module, signal output mould Block, operating mechanism module, manual operation module, electric operation module and quiet moving contact.
Domestic earthing switch mostly uses greatly the earthing switch in similar high-tension switch cabinet at present, and volume is larger, and structure is Open type.Italian COSTRUZIONI ELETTROTECNICHE S.R.L. abbreviation COET company has a whole set of DC cabinet to solve Scheme, MAT earthing switch closing time < 80ms, mechanical life 20000 times, KA Rms is up to 100kA, specified Operating voltage DC 3000V, higher than domestic direct current system voltage DC1500V.But it is larger to also result in its small product size simultaneously, Higher cost is unable to satisfy the demand of Domestic made Small cabinet body and product price economy.
Summary of the invention
The technical problems to be solved by the invention, being just to provide a kind of closed and compact-sized small volume also performance can The indoor DC grounding switch leaned on.
In order to solve the above technical problems, present invention employs following technical solutions:
A kind of indoor DC grounding switch, it is described connect switch include shell and the connection terminal module being mounted in it, Electric control module, signal output module, operating mechanism module, manual operation module, electric operation module and quiet moving contact (or Referred to as contact system), it is characterized in that: the quiet moving contact be divided into two it is separate altogether there are four copper busbar 201,202, 203 and 204, four copper busbars divide two rows 201,202 and 203,204 to be arranged symmetrically and stretch out housing rear, wherein two A upper row's copper bar (static contact 201 and 203) one meets DC power-supply system cathode another ground connection PE, under two corresponding It arranges and is equipped with mechanical connection common action between copper bar (moving contact 202 and 204) and is also electrically connected by alternate short circuit copper bar 3.
The housing cavity is divided into front and back chamber with a riser;The quiet moving contact is mounted in back cavity, four copper Row (201,202,203 and 204) divides two rows to be arranged symmetrically and stretches out housing rear;In ante-chamber, top is equipped with terminals Submodule and there is part to stretch out shell is outer, intermediate parallel is dispersed with electric control module and signal output module, bottom distribution Operating mechanism module, manual operation module and electric operation module;The operating mechanism module is described except connecting and controlling Two moving contacts 202 and 204 outside, be also respectively connected with the manual operation module, electric operation module, signal output module And electric control module, electric operation module are also connected with connection terminal module.
Manual operation module and electric operation module are separately connected operating mechanism module and realize manual operation or be automatically brought into operation, Operating mechanism module receives the signal that signal output module is transmitted by connection terminal module, and electric control module is received by connecing The divide-shut brake that line end submodule is sent controls signal and directly acts on operating mechanism module, and operating mechanism module is connected and controlled Two common actions of moving contact 202 and 204.
The electric control module is made of closing electromagnets and shunt release, when coil obtains electric, armature impact behaviour The part for making mechanism makes operating mechanism state change, and drives moving contact movement, to complete electronic separating brake or the behaviour that closes a floodgate Make.
The utility model has the advantages that quiet motive contact module of the invention includes two separate, pass through concatenated mode in actual use Connection makes circuit form two breakpoints so that increase in limited bulk the fracture that opposite inlet-outlet line is formed in separating brake away from From performance that guarantee is pressure-resistant;Meanwhile the present invention also has the characteristics that compact-sized small in size and reliable performance, and uses modularization Component, it is easily manufactured low in cost.
The present invention has the ability for closing short circuit current and opening and closing induction current, is used in DC cabinet system, when route goes out When existing short-circuit conditions, short circuit current can be linked into underground rapidly, then be cut off short circuit line by dc circuit breaker.
