Abstract
The utility model relate to a kind of can the high-voltage motor of lightning protection, high-voltage motor both sides are respectively arranged with motor main junction box and generator neutral point terminal box; The neutral point of outlet terminal is connected with zinc oxide arrester.Due to high-voltage motor internal stator winding being provided with two groups of binding posts, wherein one group of binding post is connected to motor main junction box, another group binding post is connected in generator neutral point terminal box three outlet terminals after the process of envelope star, and the neutral point of outlet terminal is connected with zinc oxide arrester.And then zinc oxide arrester is in conducting state, thus when running into thunderbolt by zinc oxide arrester release overvoltage energy, and then can effectively limit the harm of overvoltage to motor.
Description
Technical field
The utility model belongs to electrical equipment, be specifically related to a kind of can the high-voltage motor of lightning protection.
Background technology
The high-tension motor of current use does not all configure lightening protection installation, and motor takes place frequently when area uses at thunder and lightning and damages because overvoltage can produce motor winding insulation, affects motor safe operation.Thus at present eager need a kind of can the lightning-arrest high-voltage motor of lightning protection.
Utility model content
The purpose of this utility model is to overcome the shortcoming existed in above-mentioned prior art, provide a kind of can the high-voltage motor of lightning protection, there is the advantage that lightning protection is lightning-arrest, the advantage that high-voltage motor normally runs can be ensured.
For achieving the above object, the utility model by the following technical solutions: comprise high-voltage motor, high-voltage motor both sides are respectively arranged with motor main junction box and generator neutral point terminal box;
Described high-voltage motor internal stator winding is provided with two groups of binding posts, wherein one group of binding post is connected to motor main junction box, another group binding post is connected to three outlet terminals in generator neutral point terminal box, and the neutral point of outlet terminal is connected with zinc oxide arrester.
The model of described zinc oxide arrester is Y1W-1-7.6/19.
Two groups of binding posts that described high-voltage motor internal stator winding is arranged, often group is three wiring, in six outlet structures.
Six described outlet structures adopt " Y " type connection.
Described outlet terminal is the outlet terminal after the process of envelope star.
The utility model has following beneficial effect: prior art of comparing, the utility model is due to high-voltage motor internal stator winding being provided with two groups of binding posts, wherein one group of binding post is connected to motor main junction box, another group binding post is connected in generator neutral point terminal box three outlet terminals after the process of envelope star, and the neutral point of outlet terminal is connected with zinc oxide arrester.And then zinc oxide arrester is in conducting state, thus when running into thunderbolt by zinc oxide arrester release overvoltage energy, and then can effectively limit the harm of overvoltage to motor.Ensure that the normal operation of device.
Further, because six outlet structures adopt " Y " type connection, thus the insulation against ground of high-tension motor is played a protective role.
Accompanying drawing explanation
Fig. 1 is the utility model overall structure schematic diagram;
Fig. 2 is lightning arrester wiring front view;
Fig. 3 is lightning arrester connection side view.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail.
See Fig. 1, the utility model comprises high-voltage motor 1, and high-voltage motor 1 both sides are respectively arranged with motor main junction box 2 and generator neutral point terminal box 3; High-voltage motor 1 internal stator winding is provided with two groups of binding posts, wherein one group of binding post is connected to motor main junction box 2, another group binding post is connected in generator neutral point terminal box 3 three outlet terminals after the process of envelope star, and the neutral point of outlet terminal is connected with zinc oxide arrester 4.The model of zinc oxide arrester 4 is Y1W-1-7.6/19.Two groups of binding posts that high-voltage motor 1 internal stator winding is arranged, often group is three wiring, in six outlet structures.Six outlet structures adopt " Y " type connection.
(1) according to lightning arrester alternation rule, lightning arrester is selected according to the type of electric moter voltage grade and required lightning arrester and accuracy class.Its core parts resistor disc of metal oxide arrester take zinc oxide as main advanced formula, has very excellent nonlinear characteristic.Under normal working voltage, the electric current passed through only has microampere order, and when suffering overvoltage, the electric current passed through reaches kilo-ampere instantaneously, and lightning arrester is in conducting state, release overvoltage energy, thus effectively limits the harm of overvoltage to motor.Therefore generally select zinc oxide arrester.
(2) because switching overvoltage mainly produces at high-tension motor between phase and phase, so require that motor stator is star connection, namely motor is star connection six outlet, reserved six terminals when stator is produced, in U1, V1, W1 terminal access motor wire outlet box, be user-friendly to.
(3) carry out envelope star to U2, V2, W2 terminal brace, neutral point connecting line 5 connects lightning arrester.And be fixed in neutral point outlet box by lightning arrester, thus ensure that lightning arrester reliability of operation.Lightning arrester is arranged in generator neutral point terminal box, is positioned at the symmetrical side of motor main junction box.
1) select applicable motor zinc oxide arrester 4, comprise suitable electric pressure and accuracy class;
2) motor stator is six outlet structures, " Y " type connection;
3) wiring of lightning arrester in generator neutral point outlet box and machinery fixing.
The high-tension motor 1 of equipped zinc oxide arrester 4 is all star connection, so play certain protective role to the insulation against ground of high-tension motor 1.Both avoided high-tension motor 1 because insulation is breakdown and damaged, having additionally reduced various short circuit accident.And volume is little, easy installation and reliable, price comparison is cheap.
Described envelope star is treated to, and uses two lug plates 6 outlet terminal U2 and V2, W2 and U2 to be connected between two respectively.
Claims (5)
1. can the high-voltage motor of lightning protection, it is characterized in that: comprise high-voltage motor (1), both sides are respectively arranged with motor main junction box (2) and generator neutral point terminal box (3);
Described high-voltage motor (1) internal stator winding is provided with two groups of binding posts, wherein one group of binding post is connected to motor main junction box (2), another group binding post is connected to three outlet terminals in generator neutral point terminal box (3), and the neutral point of outlet terminal is connected with zinc oxide arrester (4).
2. according to claim 1 a kind of can the high-voltage motor of lightning protection, it is characterized in that: the model of described zinc oxide arrester (4) is Y1W-1-7.6/19.
3. according to claim 1 a kind of can the high-voltage motor of lightning protection, it is characterized in that: two groups of binding posts that described high-voltage motor (1) internal stator winding is arranged, often group is three wiring, in six outlet structures.
